SAINTE-ANNE-DES-PLAINES, QUE. — A federal inmate serving time for murder who vanished on Monday from a prison north of Montreal was arrested hours later in Toronto.

Correctional Service Canada said 85-year-old convicted killer Ricardo Vilches wasn’t present during head count at noon on Monday.

He was incarcerated in the minimum security unit at Archambault Institution in Ste-Anne-des-Plaines, Que., 35 kilometres north of Montreal.

An arrest warrant was issued for Vilches, who is serving an indeterminate sentence for second-degree murder.

The inmate was arrested by Toronto police around 5:45 p.m. on Monday.

Corrections officials say they will investigate the circumstances surrounding Vilches’ escape.
