A police investigation into a suspected meth lab inside an Manhattan apartment building that forced an evacuation late Monday turned up nothing more than legal bath salts, a law enforcement source with knowledge of the investigation tells NBC 4 New York.
The building was evacuated and the NYPD bomb squad was dispatched to investigate the materials.
West 54th Street between Ninth and Tenth avenues was roped off by police and dozens of people were displaced for a time.
A law enforcement source said early Tuesday that the investigation found a man in the apartment was manufacturing legal bath salts. No charges were filed and police said the investigation revealed no criminality.
