A teenager was run over and killed by a motorist while crossing a street in the south metro, authorities said Monday.

The incident occurred about 8:55 p.m. Saturday in Inver Grove Heights in the 7500 block of Cahill Avenue, police said.

The 15-year-old boy was taken by emergency responders to Regions Hospital, where he died, according to police.

Police said in a statement that the driver was cooperating with authorities and "showed no signs of impairment."

Identities of the driver and the teenager have yet to be released.

A 16-year-old boy was with the teen but not hurt, Police Cmdr. Dennis Haugland said Monday.

Police also have yet to say whether the 15-year-old was crossing at a legally designated location.
