A suspended Catholic priest who dealt methamphetamines, owned a sex shop, and occasionally engaged in sex acts with men while cross-dressed has asked a judge for leniency.

According to the UK's Metro, Monsignor Kevin Wallin of the St. Augustine Parish in Bridgeport, Connecticut first made headlines in 2013 when he was charged with dealing in crystal meth.

He was caught after selling it to an undercover officer.

He laundered the money from his drug operation through a sex shop. He also apparently engaged in 'unpriestly behaviour' with 'odd looking men' while wearing women's clothes.

'Monsignor Meth', as he has been dubbed, has now asked for leniency, citing his charitable works and more than 80 letters of support from higher ups in the clergy.

While he agreed to a prison sentence of 10 to 11 years when he pleaded guilty, he is now asking for his sentence to be reduced to four years and 500 hours of community service.
