Waterloo Regional Police say an 18-year-old male is dead after a serious collision in Heidelberg early Thursday morning.

First responders were called to the scene on Lobsinger Line around 6 a.m.

Police say the male driver from Mitchell was travelling east and not wearing his seatbelt when he lost control of his pickup truck, entered a ditch on the north side, and was ejected.

The male was pronounced dead at the scene.

His identity has not been released.

A second vehicle was indirectly involved, after the vehicle had already hit debris.

Police were notified by a passerby.

They say there was a small natural gas leak as a result of the crash. Union gas is on scene controlling the leak.

Police closed off Lobsinger Line at Durst Road and Martin Creek Road as investigators attended the scene.

Anyone who may have witnessed the collision is asked to contact WRPS.
