Three masked gunmen climbed through the drive-thru window of North Philadelphia McDonald's early today and bound three employees before fleeing with about $2,000 in cash, police said.

No one was injured during the stickup at the restaurant on the 2100 block of West Lehigh Avenue.

Police said the bandits, all armed with handguns, masked and wearing hoodies, entered about 2:30 a.m. and rounded up the employees.

After securing the worker's hands with plastic ties, they looted the cash registers, officials said. They also stole $75 in cash, a cellphone and passport from one of the employees before fleeing.

Police are still looking for the trio.
