Police have released an updated description of the suspect who threw an explosive device at a convenience store clerk in Sioux Falls last weekend, but they still don't know who they're looking for.

Information Officer Sam Clemens says a detective has been scrutinizing the surveillance video from the BP store at 3308 West Russell Street and has more information:

Clemens says the man was wearing gloves and had some type of coloring, possibly similar to eye-black, around his eyes and mouth so his skin color could not be seen.

Police say he threw an explosive device at the clerk around 10:30 p.m. Saturday, and then ran from the store.
