A man who escaped jail in a rubbish lorry a decade ago has fled prison for a second time.

Mark Chung went on the run from Ranby Prison, Nottinghamshire, in 2006 after hiding inside a waste vehicle.

The convicted drug dealer was caught but has now been reported missing from HMP Castle Huntly near Dundee.

Members of the public have been warned not to approach Chung, who has connections to the Glasgow and Merseyside areas.

A spokesman said: "We are appealing for information regarding the whereabouts of prisoner Mark Chung who has absconded from HMP Castle Huntly.

"He was reported missing at 10am on Monday and it is believed that Chung has connections in the Glasgow and Merseyside areas.

"When last seen he was wearing glasses, a grey sweatshirt, grey jogging bottoms and black and grey trainers.

"If seen, members of the public should not approach Chung and should contact Police Scotland on 101."

Chung is 5ft 9in, with a stocky build and a shaved head. He is of Asian appearance and speaks with a Merseyside accent.
