Two men with a history of child porn charges were arrested Thursday for allegedly breaching probation and bail conditions.

Keith Thornton, 42, was originally charged with possession of child porn several years ago. He was released on bail in 2010 with several conditions, including an order to stay away from any playground or facility used for children.

On Tuesday, Thornton was allegedly spotted at a youth soccer game. He was arrested on Thursday and faces charges of breaching a recognizance of bail.

In 2008, police in Germany came across an Internet chat room user offering to exchange images of child porn.

German police sent the information to the RCMP's Child Exploitation Centre in Ottawa, which forwarded the package to Greater Sudbury Police.

As a result of the tip, Thornton's home -- the same home where his wife ran a private daycare service -- was searched in July 2008.

Two computers and several storage devices were seized, though police said that there was no evidence that the childcare centre had anything to do with the charges.

Thornton was subsequently charged.

According to Sgt. Tim Burtt of the cyber crime unit, Thornton is still awaiting a trial date.

"It's still going through a lot of legal issues," he said, adding that the preliminary hearing is done and a trial date may be set for the fall.

On the same day as Thornton's most recent arrest, police arrested a 58-year-old man who has been convicted of accessing child pornography, for which he was sentenced to 14 days in jail and two years of probation, Burtt said.

Peter Mcgann, who was originally charged with accessing the pornography in early 2011, is now facing four counts of breaching probation after a member of the public allegedly saw him using a computer at the Mackenzie Street branch of the Greater Sudbury Public Library.

The accused's probation orders banned him from going to the library and accessing the Internet in any fashion.

"There's a continuing investigation to see what he was doing there," Burtt said.

According to the sergeant, both arrests stemmed from public tips, which is an important component of police work.

"There's only so many officers to police any community," he said.

Both Thornton and Mcgann were scheduled to appear in bail court Friday.
