Wellston — A brawl between the newly chosen city police chief and his ousted predecessor resulted in guns being drawn on Friday and the mayor requiring medical attention for trying to intercede, police said.

The new police chief was named about four days ago, said Pine Lawn Police Chief Rickey Collins, whose department is investigating at the request of the St. Louis County prosecuting attorney's office.

The two men began pushing and shoving each other about 3 p.m in a meeting room inside Wellston's City Hall. Collins said he did not know what they argued about, though he said the former police chief recently had been demoted to assistant chief.

Guns were pulled during the scuffle, but no shots were fired, Collins said. He said police were investigating who pulled the guns. Wellston police would not identify the new police chief, and Collins did not know his name. The other officer is not being identified because he hasn't been charged.

The mayor, Frank McNeil, tried to break up the fight but became overexerted due to a heart condition, Collins said. An ambulance arrived and he was treated at the scene. No arrests were made, Collins said, and police continued to sort out what happened.

Efforts to reach those involved in the brawl, as well as Wellston city officials and council members, were not successful.
