CHICAGO (CBS) — Chicago police officers were involved in two separate weekend shootings.

Sunday morning officers saw two men shooting into a group of people near 63rd and Halsted.

They returned fire at those gunmen, but both ran off.

One person later showed up at Mercy Hospital with a gunshot wound.

It is not clear if the person was hurt during the initial shooting or by police.

About an hour later in Lawndale officers were stopped at a light near 18th and Kostner when they say 26-year-old Danny Martinez, of Waukegan, started shooting at them from a black car. 

Martinez and a 35-year-old woman were later arrested.
