Jack Walker, 53, is being held in jail after being stopped at the airport in the capital Jakarta. It is understood the father of two – who is well known for taking meat around pubs near his home in Wythenshawe – was arrested as he was about to board a flight back to the UK. Officials allegedly found a substantial amount of methylamphetamine – commonly known as crystal meth or ‘ice’. It is believed the drug was found in a concealed compartment of a suitcase. Mr Walker, who is a diabetic, collapsed after he was  stopped.  It is understood his family are anxious he may not be receiving the correct medication to control his condition while in custody. A friend of the family said: “He is well known in the area – he drops off meat at the pubs and clubs. “The family fear he could be facing the death penalty or 20 years in jail. They are desperately trying to get help but say no one is listening. “He has a wife and two children. Apparently someone should have gone with him when he went abroad but pulled out. “He needs medication for his diabetes. Everyone around here is shocked by this. “He is not the kind of guy that you would expect would get involved in anything like this.” Another friend and neighbour, who asked not to be named, said: “We’re really shocked - it’s unbelievable. “My husband and I are devastated - we’ve known Jack for 19 years. He's never been in any trouble. I feel so sorry for him. It’s such a shame I just wish they could bring him back here.” A Foreign Office spokesman said: “We are aware of the arrest of a British national at Soekarno-Hatta International Airport in Indonesia. Consular assistance is being offered.” He confirmed that the death penalty was used against convicted drug smugglers in Indonesia. The country has some of the toughest anti-drug laws in the world with capital punishment for trafficking and 10-15 years for drug use. Mr Walker was arrested at the end of August.
