Waltham Police believe the man who allegedly carjacked a woman on Aug. 14 may be hiding in Boston, according to a WCVB-TV report that aired on the 11 p.m. news last night.

Scott Steverding, 30, of Waltham, allegedly carjacked a teenage driver in the parking lot of the CVS Pharmacy on Harvard Street. According to a Aug. 14 broadcast report on WCVB-TV, Steverding approached the girl, who was in her blue 1999 Jeep Cherokee, and threatened to stab her with a needle filled with HIV-tainted blood. Steverding then took control of the car, after the victim got out, and drove away. Steverding nearly struck the victim with the car.

Steverding also allegedly stole the woman's purse and $200, WCVB-TV said. 

As of 11 p.m. on Aug, 14, neither Steverding nor the car had been located, according to WCVB-TV. The car's license plate is 872-LV4, police said. 

Police are investigating the incident and plan to charge Steverding with attempted murder, armed car jacking and assault by means of a dangerous weapon.

Steverding is known to police and has been arrested three time in the past five months, according to WCVB-TV. In March, he was arrested on an outstanding warrant for larceny over $250 and resisting arrest.
