Halloween is months away, but a goon in a Michael Myers mask got an early start by robbing a Bronx laundry on Thursday with what police say appeared to be a fake machine gun.

“She [the clerk] was very scared. It was like a Halloween costume,” said Judy Jing, 36, who answered the phone Friday at the Laconia Avenue laundry in the Edenwald neighborhood.

“He had a gun. It looked real, but nobody knows,” Jing said, adding that this is the first time the laundry has been stuck up.

The crook was seen on video surveillance, cops said. Police say he demanded that a 51-year-old worker fork over cash from a register.

The video shows him grabbing $246 and stuffing it in a bag before he fled.

Terrified customers were still doing laundry when the crook ran in the front door, Jing said. Two of them ran out and others hid in the store.

The masked man was last seen speeding off in a Jeep Liberty SUV.
