A Scarborough teacher is facing a new charge Monday after allegedly entering into a sexual relationship with at least two female students under the age of 18.

Toronto Police say a teacher at Bendale Business and Technical Institute was originally charged with sexual exploitation on June 13 for allegedly having a sexual relationship with a female student.

The teacher was subsequently released on bail with the conditions that he refrain from being in a position of trust or authority to anyone under 18.

But on Monday, the suspect was arrested once again by police for allegedly engaging in another sexual relationship with a female minor, police say.

Authorities did not say when the reported transgression took place but indicated that they had received new information after news of his first arrest made headlines.

Investigators say the suspect has been a teacher with the Toronto District School Board since 2000 and has also taught at Martingrove Collegiate Institute. Police believe there could be more victims and are asking anyone with information to contact police at 416-808-2922 or Crime Stoppers anonymously at 416-222-TIPS (8477).

Matthew Elms, 39, of Toronto, faces two counts of sexual exploitation.
