The SWAT team was called to a hostage barricade situation in Chicago's East Side neighborhood. Police say someone fired shots at an officer near the 10300 block of South Avenue N in the East Side neighborhood at 3:38 a.m.

The officer was not injured and police did not return fire, but the suspects reportedly fled into nearby homes.

The SWAT team was called in as police worked to locate the shooters. The streets and alleys around the homes were blocked up.

Throughout the morning, people were seen walking out of the homes and placed in handcuffs. Police said they were taking every precaution.

Neighbor Mary Arana says she heard the gunshots early this morning. She awoke to the sound of several shots but she says she was too scared to look out her windows.
