An Everett man wanted by Malden police on suspicion of attempted murder tried to jump from the Tobin Bridge Saturday morning while fleeing Chelsea police, but became stuck in construction safety netting, authorities said.
Malden police tracked Mostafa Laassal’s cellphone and alerted Chelsea officers that he was in the area of Everett Avenue, Chelsea Captain Keith Houghton said.
Officers saw Laassal, 49, parked in the Market Basket parking lot of Everett Avenue at about 9:30 a.m. When they approached him, he fled in his vehicle.
Police pursued Laassal at a low speed onto the upper deck of the bridge, Houghton said. As his car ascended the bridge, he swerved multiple times and came to a stop at least twice.
Laassal left the vehicle with a knife, jumped over the bridge’s railing, and became stuck in construction netting on the lower deck, police said.
Houghton said the suspect did not approach officers with the knife.
An officer on the upper deck secured the suspect in the netting while officers on the lower deck were able to pull him out, Houghton said.
Authorities took him to Massachusetts General Hospital with serious leg injuries, police said.
Houghton described the alleged attempted murder as a domestic case involving a knife, but had no further information.
Chelsea police charged Laassal with motor vehicle infractions.
Houghton said he expects Malden police to charge him with attempted murder and take him into custody when he is discharged from the hospital.
State Police briefly shut the bridge to traffic during the rescue, but all lanes were reopened and traffic was flowing smoothly shortly afterward, Trooper Dustin Fitch said.nicholas.jacques@ globe.com.
