MONROE, La. (KNOE) – Authorities are continuing to investigate the circumstances surrounding an explosion that injured a Monroe business owner on Thursday.

Monroe police are now asking for public assistance in the case.

They are asking homeowners and businesses in and around the area of the 2500 block of Ferrand, to check their surveillance systems over the past 72 hours for suspicious activity. Anyone with any information is asked to call Monroe police.

According to a family member of the victim, the beauty school’s owner was injured by the explosion. Monroe PD described the victim’s injuries as minor.

KNOE talked to one of the school’s students who described the incident.

“The owner was actually out there beside the trash can. It was on fire and they said he had thrown some boxes on top of it and it just exploded. So it burned him a little bit and then, whenever the fire trucks came, we were looking back out there and we saw that they had pulled out what looked like a crockpot out of it and we heard that there was some kind of spray cans in there as well,” she said.

Monroe PD says the investigation is ongoing. They say the Monroe Police Department is being assisted by the Louisiana State Police, Federal Bureau of Investigation (FBI), Alcohol, Tobacco, Firearms and Explosives (ATF), and Homeland Security.
