State and Boston Police say a man driving a stolen car from Medford sped away from a state trooper today, eventually causing a four-way crash on I-93 and then fleeing on foot into Dorchester's Port Norfolk section, where police found him hiding under another vehicle.

According to State Police, a trooper on Adams Street noticed a Dodge Caravan that had been reported stolen and began "a slow speed chase" around noon today. The driver refused to stop, then sped up and raced onto Morrissey Boulevard going the wrong way. In a statement, State Police said:

"At that point we terminated the pursuit but continued attempting to monitor the vehicle's path of travel. Reports indicated that the suspect vehicle continued from Morrissey to the rotary and then onto Route 93 going southbound in the northbound lane. The wrong way operator is believed to have caused a four-car crash on Route 93 north prior to Freeport Street and got off the highway in the Neponset area."

State Police report Richard Saunders, 48, of Reading, drove into Port Norfolk, where officers found him under a car on Taylor Street. They add nobody appeared to be seriously hurt in the crash. Saunders was taken to Boston Medical Center with minor injuries.
