There were some tense moments in Timmins Thursday after police were called to an apartment building on a landlord-tenant matter and ended up finding explosive materials in one of the units.

Materials found included a blasting cap and evidence of dismantled ammunition.

The building, located on Balsam Street North, was evacuated and Ontario Provincial Police's explosive disposal unit was called in. It is described as a house split into units, rather than a large apartment complex.

Provincial officers arrived around 9 p.m. and were able to safely seize, contain and dispose of the explosive devices.

"As part of the investigative process undertaken by the Timmins Police, a search warrant was executed at the Balsam Street building where explosive devices, firearms, ammunition, and suspected stolen property was located and seized as evidence," said police in a news release Friday morning.

The matter remains under investigation by the local criminal investigations division, but the residence and immediate area have been released by police.

Anyone with information in relation to this matter is urged to call the Timmins Police without delay at 705-264-1201 or anonymously by means of the Crime Stopper tip line at 1-800-222-8477 or online by means of www.p3tips.com.
