The 15-year-old got onto a Metro Route 49 bus around 5:30 p.m. He later told officers the female bus driver greeted him by saying, "Hey, little boy. Where are you going?"
According to the police report for the incident, the driver told the teen there was a report of a runaway boy who looked just like him and he would have to stay on the bus.
The teen, afraid the driver was going to detain him, called his mother on his cellphone. When he didn't get an answer, he tried to get off the bus a stop early at Bellevue Avenue and East Pike Street.
As the teen was exiting the bus through the front door, the driver closed the door on his ankle, according to the report.
The teen told officers the driver appeared to be putting all her strength into the lever that closes the door in order to keep him from leaving the bus.
The teen finally pulled his ankle free and walked home, calling his mother again as he went.
The teen's mother filed a police report, and officers documented the mark on the teen's leg from the door closing on it. She told officers she was also going to lodge a complaint with King County Metro.
The Seattle Police Department has not followed up on the incident or assigned anyone to the case.
Metro received the complaint from the teen's mother on Wednesday and is currently investigating.
