Not guilty plea entered on SFPD sergeant's behalf while he's in detox

A plea was entered on Thursday for a San Francisco police sergeant accused of trying to rob a pharmacy in San Mateo. 

SFPD Sgt. Davin Cole appeared virtually for his arraignment because he is at a detox treatment center. 

Cole is accused of trying to steal painkillers at a Rite Aid store. Investigators say he had a loaded gun at the time and that he resisted arrest. He is on unpaid leave from the department. 

A preliminary hearing is set for February 7.
