The bus was stolen just before 11 a.m. along Martin Luther King Jr. Way and Myrtle Street. During the chase, the bus reached speeds of 75 miles per hour as it raced through the south end.

The incident ended at 22nd Avenue South and South Massachusetts Street, when the bus drove over the sidewalk and up an embankment.

During the escape, police say the bus struck at least five other cars and grazed many other parked cars. In one collision at Martin Luther King Jr. Way and Alaska, two people were trapped inside.

They were both extracted from the severely damaged car and were taken to Harborview Medical Center. Harborview says a 22-year-old man has been upgraded to serious condition with a head injury, and a 19-year-old woman was in serious but stable condition.

From a separate collision, a 27-year-old woman was at Harborview in satisfactory condition with knee pain. Her 7-year-old son suffered a bruised forehead. Her 21-month-old daughter was uninjured.

And in a third collision, a 36-year-old man from Seattle was being assessed for a possible head and neck injury and was in satisfactory condition.

A 47-year-old man, who was a nearby pedestrian, was also brought to Harborview with a toe injury.

The 21-year-old man who allegedly stole the bus was also taken to Harborview for treatment and was in satisfactory condition.

There were a few other minor injuries treated at the scene from other cars getting grazed by the bus.

The bus made it about two miles before running up an embankment at 22nd Avenue South and South Massachusetts Street, at which point the driver tried to run away on foot. But police were able to arrest the man, who was described in his late teens.

It All Began With A Fight

Police say the incident apparently began with a fight on the bus as it traveled along Route No. 42. The Metro driver, who is a 15-year veteran with a good driving record, then pulled the bus over and asked everyone to get off the bus -- standard procedure, according to a Metro spokesperson.

However, one person refused to leave.

The bus driver then went back on board to try and get him to leave, but the man became violent and began pounding on the walls and windows of the bus. The driver felt threatened and left the bus.

At that point, police say the man went up to the driver's seat and drove off. The bus driver actually flagged down another car and had them follow behind as he called police.

Metro would not release the name of the driver, only saying he's from Seattle, is a "very popular" driver, and is shaken up over the ordeal.

Shaken witnesses who happened to be driving on the street as the bus sped by tell us they barely managed to get out of the way as the bus swerved in and out of traffic at nearly 75 mph. "It was like something out of a movie," one witness told KOMO 4 News.
