Two Michigan police officers accused of brandishing their guns and badges, then robbing and assaulting two civilians, were released from custody but remain suspended from their jobs, officials said.

The two officers, veteran sergeants from the Detroit Police Department and the nearby St. Clair Shores Police Department, are accused of robbing two men at gunpoint and assaulting one at a gas station earlier this month.

The men were both arrested over the weekend, but authorities have not released their names. Neither sergeant has yet been charged or appeared in court, prosecutors said.

"We are working on the warrant and the case remains under investigation," said Maria Miller, spokeswoman for the Wayne County Prosecutor's Office.

The two cops allegedly approached the two civilians at a gas station at 4:45 p.m. on Sunday, July 21, according to Detroit Police Chief James Craig.

At a press conference held Monday, Craig said the cops were dressed in plain clothes and driving a black pickup truck, but had badges around their necks and their guns drawn when they allegedly accosted the two men.

They detained the citizens, stole an undisclosed amount of cash from one, and a cell phone and wallet from the other man, who was subsequently pistol whipped, Craig said.

The alleged victims called police and reported the robbery. Police initially believed the suspects were impersonating cops, but an officer recognized one of the men from a photograph taken by a witness.

Authorities would not comment on the motive. However, local media, citing police sources, said the officers believed the men were connected to the robbery and assault of one cop's daughter.

Lawyer Todd Flood, who represents the St. Clair officer, did not return phone calls seeking comment.
