A female staff member at a homeless referral centre in downtown Toronto has been taken to a trauma centre after a reported assault, according to Toronto police.

The incident occurred at a city-owned facility around 2:30 p.m. near Peter and Richmond streets.

Witnesses at the scene told CP24 that the woman was possibly hit with some sort of object, though police did not confirm that detail.

Paramedics say the woman, who is believed to be in her 30s, was suffering from possibly life-threatening injuries. Her condition was later upgraded to stable.

A male suspect is in custody in connection to the incident. Police said he is believed to be about 40 years old.

Toronto police did not provide information on what charges, if any, he will face.
