MONTREAL -- A lockdown has been lifted for two high schools in Lachute, according to the local school board.

Students and staff at Laurentian Regional High School and Polyvalente Lavigne -- both in the same building off Argenteuil Avenue in Lachute -- were placed under lockdown after reports a man who may have been armed with a knife was spotted nearby at about 1:30 p.m. Thursday. 

The schools were put on lockdown and police were been searching the streets nearby. The investigation revealed the person believed to be carrying the knife probably didn't enter either school, nor did they threaten anybody. Witness testimony revealed the person had been seen walking through a wooded area nearby.

The Wilfrid Laurier School Board emailed parents at 3:45 to tell them the order had been lifted. By 5 p.m., students were allowed to go home. 

No arrests had been made by then., though the SQ says officers met with a teenager who resembled the suspect. 

The investigation is ongoing.
