The investigation is centered around a building that houses several businesses, including a hair salon and the local chapter of the NAACP.

“The NAACP looks forward to a full and thorough investigation into this matter by federal agents and local law enforcement,” the organization said in a statement made on Tuesday.

The FBI will decide if this was a hate crime.

There were no deaths or injuries resulting from the explosion, and only minimal surface charring to the exterior wall of the building, according to FBI Denver.

Police are looking for a white man around 40-years-old who was driving an older model dirty white pickup truck with wood side paneling.

If anyone has information regarding the above incident or individual, please call the FBI Denver tip line at (303) 435-7787.
