Hamilton paramedics say three female inmates at Hamilton-Wentworth Detention Centre received medical treatment Thursday night for suspected overdoses.
Emergency crews were called to the jail on Barton St. shortly before 8 p.m.
EMS superintendent Dave Thompson says two of the women were taken to hospital by ambulance and the other by a corrections staff member.
Hamilton police Cst. Jerome Stewart says the victims, two 22-year-olds and a 33-year-old, were all sharing a cell.
“They have since been medically cleared and are back at the Detention Centre,” said Stewart.
These latest incidents come just four weeks after a woman in her thirties died of a suspected drug overdose at the jail.
Thompson says there were 20 overdoses in the city of Hamilton between May 1 and 7.
