Birmingham police are investigating an altercation involving Birmingham mayor William Bell and council member Marcus Lundy that sent both men to the hospital.

Paramedics were seen leaving the mayor's office shortly before 11 a.m. City officials tweeted shortly after noon that Bell was undergoing a CT scan and MRI. The president of the city council shared with reporters photos that showed bloody scratches on Lundy's leg.

Mayor Bell, 66, reportedly suffered injuries to his throat and knee. He was treated and released from the hospital today.

"Thank you for all the thoughts and prayers," the tweet from the city's official account read.

Officials said the two went into a back room to talk about a consultant. The discussion became heated and the mayor tried to leave. No one else was in the room. At some point, Lundy put his hands around the mayor's neck and tried to pull him back, squeezing and leaving marks, a source told AL.com.

It was reported Lundy said Bell talked to Regions Bank, Lundy's employer, and said Lundy should be fired. Bell's office denied it.

City spokeswoman April Odom issued this statement: "The Mayor is currently recovering at a local area hospital. A formal police report has been initiated and will be ready for release in the next hour. From there, the magistrate will swear out a warrant for the arrest of Councilor Lundy. When approached by Birmingham Police, Councilor Lundy refused to give a statement."

Council member LaShunda Scales this afternoon provided AL.com with audio from the budget and finance committee. The audio includes Scales asking Patton about a vehicle -- a Ford Expedition -- that had been loaned to the council and was taken back without the council being notified.

Odom today told AL.com Lundy drove a city owned vehicle and the city law department asked that the vehicle be returned.

"There was some documents from my office in the back," Lundy said, according to the recording. Patton said Lundy could retrieve them.

Scales then asked why Patton did not discuss the retrieval of the vehicle with council members.

"I'm not going to sit here and be questioned and badgered," Patton replied. Patton then asked if he is being recorded and does not answer when Scales asks how he is badgered.

When the questioning persists, Patton leaves the meeting.

"I think it's real unfortunate that that's the way we choose to govern ourselves," Scales said.

Lundy was elected to the District 9 seat in 2013 after Roderick Royal decided not to seek re-election.
