Leaders of a Bloomington mosque damaged during a bombing in August have released videos of the explosion in hopes of generating tips that could help law enforcement catch those responsible.

The FBI said somebody set off an improvised explosive device around 5 a.m. Aug. 5 inside the Dar Al Farooq Community Center on Park Avenue as about a dozen people were in the building for morning prayers.

No one was hurt, but the incident left congregants and neighbors shaken.

Days after the bombing, the FBI offered a $30,000 reward for information that might lead them to suspects, but nobody has been arrested.

On Tuesday, Minnesota chapter of the Council on American-Islamic Relations (CAIR-MN) released videos that show the moment the device went off as a person walks down a hallway.

Cameras inside the center caught the blast after somebody threw a pipe bomb into an office of an imam. The explosion left the cracks in the mosque’s walls and caused other damage.

“The videos show the forceful nature of the bomb,” CAIR-MN Executive Director Jaylani Hussein said in a statement. “We request law enforcement agencies to apprehend the attacker and bring them to justice.”
