Calling the investigation its top priority, the FBI said Wednesday that it is offering a $30,000 reward for information leading to the conviction of anyone responsible for the bombing of a Bloomington mosque this month.

The bureau’s Minneapolis division has been investigating the Aug. 5 explosion at the Dar Al Farooq Community Center. In a statement posted on Twitter Wednesday, the FBI said the new reward is unrelated to those offered by the Council on American-Islamic Relations and the local Muslim American Society.

The FBI said an improvised explosive device caused the blast, which occurred inside the office of an imam at the center. No one was hurt in the explosion.

The FBI is still asking those with any information on the explosion to call 1-800-CALL-FBI and thanked “the public for their cooperation and the critical information they have provided to our investigators.”
