Sarnia police have issued the all-clear after a bomb threat was received at Lambton College on Monday.
Police were called to the London Road school just before the noon hour.
A shelter in place order was in effect for about 90 minutes at the college and neighbouring Progressive Auto Sales Arena, but the threat was determined to be unfounded.
An "all-clear" was also issued via myCNN.
The investigation into the false threat continues at this time.
Lambton College said residents with kids in day camps had the option to pick them up at the Wellington Street entrance if they choose.
Anyone with further information is asked to call the Sarnia Police Service's Criminal Investigation Division at 519-344-8861 ext. 5300.
