(CNN) -- A man is in custody on charges of felony arson after allegedly driving a car bomb into an Illinois bank Friday evening.

David A. Whitesell, 48, of Blue Island, Illinois, was arrested after witnesses at the scene identified him, the Lockport Police Department said.

Whitesell drove his car into the front entrance of a PNC bank in Lockport, police said. The car exploded as he walked away, police said, adding that he used the same material found in fireworks.

No injuries were reported because the bank was closed and unoccupied at the time, authorities said.

Whitesell is being held on charges of felony arson and felony criminal damage to property with an incendiary device.

His motive is unknown, according to police.
