BOSTON -- Police were searching for suspects Tuesday after a double stabbing inside an MBTA Red Line train station overnight.

NewsCenter 5's Gail Huff reported that the stabbing occurred just after midnight, and the victims were taken from the station at the Park Street stop.

Police said the two victims were transferring between the Green Line and Red Line platforms when a fight apparently broke out with three other individuals. Two knives were recovered from the scene.

The identities of the two victims were not known. One was said to have life-threatening injuries, with a stab wound to the stomach, and the other suffered less serious injuries.

MBTA police were looking for three suspects, two men and a woman, who fled the area after the stabbing.

Red line service was running on a normal schedule Tuesday morning.
