A PGW crew was checking for a gas leak at a house in Southwest Philadelphia Monday morning when they stumbled across a marijuana growing operation, police said.
The home, on Reedland Street near 58th, was unoccupied when the workers arrived.
The crew called the cops around 10 a.m., and police said the operation took up the second floor of the home as well as the basement.
Fifty marijuana plants were found inside the house, along with specialized lighting, a generator and a filtration system.
It was unclear Monday night whether police contacted the owner of the house, or if any suspects were taken into custody.
