An underage male was arrested on suspicion of aggravated robbery Tuesday after a woman told Colorado Springs police that she was attacked in a King Soopers restroom, threatened at knifepoint and robbed.

Police did not release the alleged robber's identity because he is a juvenile.

The robbery allegedly happened at the King Soopers on 2910 S. Academy Blvd. about 9:44 p.m., police said.

Police searched the area and shortly after took a juvenile into custody that matched the alleged robber's description, police said.
