MINNEAPOLIS (AP) — The three other officers on the scene when a member of the Minneapolis police force pressed his knee on George Floyd’s neck are being charged with aiding and abetting a murder, and the murder case against the main officer is being upgraded to second-degree, a newspaper reported Wednesday.

The Star Tribune, citing multiple unnamed law enforcement sources, said Derek Chauvin would face the more serious charge in the death of George Floyd, who was handcuffed on the ground.

Three other officers at the scene — Thomas Lane, J. Kueng and Tou Thao — were charged with aiding and abetting second-degree murder, the newspaper reported, again citing sources who spoke on condition of anonymity.

Some of the rockiness of the days since Floyd’s death May 25 dissipated on Tuesday night, with demonstrations continuing around the country, but without major reports of violence.

New York police said they arrested about 280 people on protest-related charges Tuesday night, compared with 700 a day earlier.
