Toronto police are asking for the man responsible for four sexual assaults in the downtown area to surrender.

Police are hunting for 34-year-old Thomas Reardon who they believe sexually assaulted three women in the span of six days last month and another woman back in April.

Three women, between the ages of 18 and 40, reported that they had been assaulted as they walked alone. Two of the alleged attacks took place early in the morning, while a third happened around 2 p.m.

One victim reported being attacked twice in the same day.

Detective Constable Sandra Arruda told 680News Reardon should be considered a danger to the public.

“I fear that he is unpredictable. He’s definitely a public safety risk and he needs to be apprehended immediately,” said Det. Const. Arruda.

Police believe that if Reardon is not arrested, the attacks will continue.

“What we know about Thomas Reardon and how he has attacked his victims, we have strong beliefs that there will be more,” Arruda explained.

The attacks happened in the area from Yonge Street to Parliament Street and from Wellesley Street to Dundas Street.  

Police say there may have been other attacks they do not know about yet.

“We believe there may be further victims and we are asking them to come forward and file a report,” Det. Const. Arruda said.

It is believed that the suspect lures vulnerable women with the promise of drugs and then sexually assaults them

Police say the suspect was caught on security camera leading one of the victims to a secluded area.

“We identified him through assistance from the public using surveillance video and witnesses that come forward,” Arruda said.

Investigators say if you spot Reardon, do not approach him and call 911 immediately.
