The Cleveland City Council voted to reinstate Lieutenant Steve Tyson on Monday.
Tyson had been accused violating department policy while intoxicated.
At today's city council meeting, Cleveland Mayor Tom Rowland said Tyson told him he had in fact taken a pain pill that was in the possession of his son, in order to treat recurring kidney stone pain.
Rowland said Tyson had taken the pill the night before and went to work the next day. Tyson later tested positive for the unnamed drug.
Rowland also pointed out at Monday's meeting that the drug Lt. Tyson tested positive for was not specifically prohibited in the department handbook.
While Lt. Tyson was not at Monday's meeting, many people showed up to give the 27-year veteran of the police department their support.
They also expressed concern that the recent news of Tyson's firing, reported in many local media outlets, including NewsChannel9
, blemished his character. Tyson had not been accused of a single department violation since he joined the force in the mid-1980s.
Many people who couldn't attend wrote letters of support to the council. Tyson's wife also penned an impassioned plea on his behalf.
The council would not say exactly when Lt. Tyson would be back on the job.
