Police have launched a nationwide poster campaign to trace a man described as dangerous and predatory.
Police forces across England and Scotland are working together in an effort to track down 47-year-old absconder Ivan Leach, who was born in Preston.
Leach, also known as Lee Cyrus, went missing from North Sea Camp open prison, Boston, Lincolnshire, on Tuesday October 9 after going on day release.
It is believed he has committed a serious sexual offence in Tayside, Scotland, while at large.
Posters will appear in shops, community centres, hospitals and on bus and train stations. The posters will also be put up on all Preston Buses.
A £3,000 reward has also been offered by the charity Crimestoppers for information leading to his arrest and conviction.
Officers have warned Leach should not, under any circumstances, be approached as he poses a significant risk.
The last believed sighting of Ivan Leach was in Nottingham City Centre at 11:20am on October 20 at a cash point outside Barclays Bank on High Street. However, forces across the UK have received over 100 possible sightings since he went missing.
Leach was born in Preston and has connections across the city as well as in South Ribble.
He is known to have been in the city on a number of occasions since he absconded, but he could be anywhere in the country. Enquiries are also ongoing in Nottinghamshire, Lincolnshire and Tayside.
Detective Superintendent Paul Withers from the Force Major Investigation Team said; "While Leach remains at large he continues to pose a serious threat to members of the public. He has previous convictions for burglary, sex offences against a young girl, assault and robberies in which he has targeted elderly people in their own homes.
"We believe he could be sleeping rough and travelling extensively throughout the country, most likely on public transport – alternatively, he may be being housed by someone he knows.
"I would like to warn anyone who may be harbouring him that if they know where he is, and they fail to notify police, action will be taken against them.
Leach is described as white; around five feet 11 inches tall, of stocky build with cropped hair and hazel eyes. His has a distinctive scar on his top lip under his nose and two distinctive tattoos, one with the name ‘Annette’ on the bicep of his left arm and a figure of a barbarian woman on the back of his right shoulder blade.
Ivan Leach changed his name to Lee Cyrus in 2007 but could be using either name.
