A Toronto man charged in connection with the sexual assault of a young boy last month is facing four additional charges after police say another victim has come forward.

Police say the victim, who was between seven- and 11-years-old at the time, was sexually assaulted while attending a home daycare located in the area of Danforth and Victoria Park Avenues. The incident happened between January 2003 and December 2007.

The same boy was then allegedly sexually assaulted again by the same man while under the care of a different home daycare located at 155 Heale Ave., police say. The incident happened between January 2007 and December 2011 when the boy was between 11- and 15-years-old. Police say the boy was also shown a sexually explicit video. 

The sexual assault investigation is ongoing and police believe there may be more victims.

"At the end of the day, we are concerned about the safety of these kids who have had contact with him," Det.-Const. Conrad Wong told reporters on Monday. "Regardless of whether or not they wish to proceed criminally with anything, we would still like to put them in contact with our support networks."

Wong added that the man was not involved with the daycares' operations, but had access to the children.

Dewan Syed Mosiur Reza, 69, was re-arrested on Monday and charged with two counts of sexual assault and two counts of sexual interference. He was scheduled to appear in court Monday afternoon.

Reza was previously charged with a number of offences in connection with the sexual assault of a six-year-old boy. 

Police previously said the incident happened in the Danforth Islamic Centre, located in the area of Danforth and Victoria Park Avenues, on May 3. It was alleged the boy was shown a sexually explicit video before being sexually assaulted.
