LONDON, Ont. -- A Western University professor has been charged in an online luring investigation.

Police in London, Ont., arrested a 59-year-old man on Monday who police say is linked to an investigation that launched July 12.

A search of a home also turned up four firearms and a small amount of marijuana.

Graham Wagner is charged with two counts each of telecommunication with person under or believed under 16 years for specific criminal offences and telecommunication with person under or believed under 18 years for specific criminal offences, as well as weapons and drug charges.

A university spokesperson says Wagner has taught at Western since 1990 in the department of physiology and pharmacology.

Western says the professor is suspended "pending a review of the matter."

An online faculty profile says he earned a bachelor's degree in science at Concordia University before going to Simon Fraser University for his master's and PhD.
