Two cars pulled up outside the Ranza Club in Royston Road at about 1930 BST on Saturday. The occupants entered the pub and attacked customers. Three men were taken to hospital after they were attacked as they drank in a bar in Glasgow at the weekend.The injured men, aged 58, 55 and 49 were taken to Glasgow Royal Infirmary.
Police said were keen to trace a distinctive lime green Audi they believe was one of the cars involved in the incident. The 49-year-old man was later discharged following treatment. The other two men remained in hospital although their injuries were not thought to be life-threatening. The cars involved were described as a silver coloured Vauxhall Vectra or Astra and an older lime green coloured car, thought to be an Audi. The occupants of the cars were all men, in their early twenties and were wearing hooded tops. "Three men have been left badly injured in this attack and it is imperative we trace the people responsible. "There are shops nearby and I would appeal to anyone who may have been in the area at the time of the attack or who may have noticed the cars to contact us as a matter of urgency. "

Gordon Horsfall, 28, phoned an associate to deliver the gun and bullet-proof vest after a row at a busy nightclub on Sauchiehall Street, Glasgow. Two people were hurt as he opened fire. He is now starting a six-year jail term as well as facing extradition to Spain over a stabbing.Gordon Horsfall phoned an accomplice to deliver the gun and a bulletproof vest after a confrontation with two men inside the club. The gun and vest were delivered by taxi before he opened fire at random. One women passer-by was injured by a ricochet and was only saved from serious injury because the shot bounced off her necklace. Horsfall, 28, then turned to doorman Anthony Nyangweso and shot him through the hand before fleeing in a taxi. Last night, Horsfall was behind bars after being sentenced to nearly six years in prison for the cowardly attack. He went on the run after the shooting and was captured in July when armed police posing as postmen raided an exclusive block of flats in Glasgow's west end. He faces extradition to Spain after being accused of a vicious knife attack on a man in Tenerife. It is understood he fled to a bolthole on the holiday island after the shooting in July 2004 but returned to Scotland early this year to look after "business" interests. CCTV pictures show Horsfall - wearing the bulletproof vest - arriving back outside Blanket nightclub in Sauchiehall Street, Glasgow. He phoned a friend and got him to deliver the gun and vest in a taxi. Terrified clubbers, who have spotted the weapon, run from the scene in panic. Next, the gun-toting gangster appears to be scouring the street, trying to identify a target.
He is shown shooting into the crowd of people around the club entrance before turning to flee. He then opens the door of a waiting taxi before jumping in and making his escape. The operation followed several weeks of surveillance on Horsfall, who officers said had "holed up" and rarely left the flat after returning from abroad. At the High Court in Glasgow, Horsfall admitted assault and reckless and culpable discharge of a shotgun outside Blanket, now renamed The Classrooms. He had been at the club with two Asian friends and, in a row with another group of Asian men, he was told he was going to be shot, prompting him to make the call for a gun.
The court was told he collected the items around 3.30am then opened fire on the group outside the club - firing around four times.

overdose kits given to heroin addicts have saved eight lives, leading to calls for them to be provided for thousands of addicts in Scotland.
About 300 of the kits – syringes loaded with the drug naloxone – have been given to addicts' friends and families under two Scottish pilot schemes. Similar action has sharply cut deaths in Berlin, San Francisco and Chicago.
The pilot schemes, in Glasgow and South Lanarkshire, involve take-home doses of naloxone, a liquid that is injected and blocks the effects of opiates. It will keep a heroin user who is slipping into a potentially fatal coma alive for up to 20 minutes.
Under the pilots, which have been running since last April, with the cost of around £40,000 funded by local NHS boards, family members and friends of drug users are given training on how to detect the early signs of an overdose and on basic resuscitation techniques.
There have been six successful uses of the drug in Glasgow and a further two in South Lanarkshire.
But one of Scotland's leading drug experts has voiced grave fears that the drug will only encourage even more reckless drug abuse among Scotland's estimated 50,000 heroin addicts.
Neil McKeganey, professor of drug misuse research at Glasgow University, also believes giving drug users' families needles to take home will put children in danger and says the pilots are not being properly evaluated.
With the number of drug deaths hitting a record high of 421 in 2006 and a similar figure expected for 2007, experts say naloxone kits should be given to thousands of addicts' relatives and friends around the country.
Dr Jane Jay, chairwoman of the National Drug Death Forum, said: "This drug has, in a number of cases, made the difference between life and death. The cost is relatively low, but I would also ask 'what price a life'?"
She is now urging Kenny MacAskill, the justice secretary, to approve a national roll-out of naloxone among all heroin addicts in Scotland.
