A cell phone video captured the flames in an alley next to a house in the 13500 block of South Buffalo Avenue just after midnight. Police confirmed there were multiple fires set overnight.

ComEd crews worked to restore power after the fires downed cable lines.

It was a similar story this weekend.

As CBS 2’s Marissa Parra reported Sunday, garbage cans were also set on fire overnight Saturday. Flames were shooting from the alley between Buffalo and Burley avenues from 133rd Street south to 134th Street.

Police said three different fires in the area have been ruled arson.

Several homes were left without power and internet service for Easter dinner, because the fires spread to utility poles and scorched the electric lines and cables running through them.

Neighbors reported loud bangs, like either gunshots or fireworks, before watching the alleys catch on fire.
