Officials say fire that destroyed the haunted house attraction at Six Flags amusement park was electrical and was accidental.

Prince George's Fire Department spokesman Mark Brady says the blaze, reported shortly before 7 p.m. on Wednesday, caused an estimated $2 million in damage.

No other attractions were damaged, and there were no injuries reported.

Brady says it took 60 firefighters about 45 minutes to extinguish the blaze.
