Calgary police are investigating a serious collision that occurred in the early morning of Jan. 28.
Police said the collision occurred in the 1500 block of 36 Street S.E. near 16 Avenue S.E. at around 4 a.m.
According to a news release, a four-door sedan was travelling southbound when it veered to the right side of the road and struck a parked and unoccupied SUV.

The man is currently in serious condition, police said.
