CLEVELAND - A neighborhood is on edge while police search for answers.  Detectives are investigating a possible bomb that was thrown onto a porch, damaging a home on Cleveland’s east side.

No one was hurt.  Cleveland police say they are investigating the incident as an aggravated arson.

"I heard a big boom," explained neighbor Richard Mason.

Mason says he was watching the Cavaliers game around 8:30 p.m. Monday, when he heard a loud explosion outside on East 133rd Street in Cleveland’s Collinwood neighborhood.

"So I got up and looked out the window, then I came and looked out the door, but I didn't see anybody over there, and I looked down this way and I saw a car turn around going that way," Mason said.

The sound he heard came from across the street.  Cleveland police say someone threw some type of explosive device onto a porch.

The blast broke windows in the house, created a hole in the porch and ripped aluminum siding off the side of the house.  Mason says his wife woke up later in the evening and saw the street blocked off and fire and police investigators everywhere.

"She woke up, seem like it was the bomb squad out here, she said they had the whole street blocked off with lights flashing everywhere," he said.

The woman who lives in the home did not want to speak on camera.  She did tell Fox 8 she was asleep when she heard the blast.  She went downstairs to see glass everywhere and siding strewn across the porch and yard.  She also says her 12 and 22-year-old sons were also home at the time.

According to police, a witness told them that he saw a van drive by several hours earlier and that someone pointed a gun at the home.

The woman who lives in the home says she was unaware of that detail.  She also says she has no idea who would want to target her or her family.

"It's getting to be like the wild, wild west, you know...when it get that close to your home or your house, you get really concerned, so it kind of bothered me all day," said Mason.

Fire investigators evacuated the home for a while and checked it for more explosives, but none were found.

Investigators say they are still trying to determine what materials were used to make the device.
