York Regional Police say the King Campus of Seneca College has been safely evacuated after a threat was called in earlier on Wednesday afternoon.

The school was originally placed under a lockdown after the call came in around 2pm for what police say was a 'threat'.

They wouldn't say whether the threat was weapons related or explosives related.

So far there have been no injuries reported.

Evening classes have been cancelled, but there's no word yet on what will happen with classes for tomorrow.

Cops continue to search the property.
