A Florida public works office was evacuated Monday after a man handed over an envelope containing white powder to pay his water bill.

After emergency crews investigated, they determined the powder was actually crack cocaine.

Sheriff’s deputies in Volusia County said customers often drop off envelopes on the counter of the Deltona Water office to pay their bills.

But it’s apparently uncommon for customers to leave envelopes without statements that contain clear plastic bags with 3 grams of illegal drugs inside.

The man left the water office on a bicycle, deputies said, but they captured his image on surveillance video as he fled.
