A Hoboken emergency medical technician was stabbed in the stomach this afternoon while responding to a call, sources with knowledge of the incident said tonight.

The 26-year-old woman was inside a public housing complex building on Jackson Street at 4:50 p.m. when a man came up from behind and stabbed her, according to two sources who were not authorized to speak about the incident.

A Hoboken police sergeant who is authorized to provide information was not immediately available to provide details on the incident.

The EMT, who was on a crew with two other Hoboken Volunteer Ambulance Corps members, was taken to the Jersey City Medical Center, where she is under observation, JCMC spokesman Mark Rabson said.

The 26-year-old was placed in her own HVAC ambulance and JCMC paramedics got on the ambulance about halfway between Hoboken and the JCMC and began treating her, Rabson said.

It is believed that the initial call for an ambulance from the Hoboken location may have been a hoax, since person who requested an ambulance never called for another one, a source said.
