Baltimore police have handed state prosecutors the findings of an internal investigation into the death of a black man who suffered spinal injuries while in custody, officials said on Thursday.

The report was turned over to the state's attorney a day earlier than expected, Police Commissioner Anthony Batts told a news conference. Prosecutors have said they would conduct their own probe before deciding whether to charge six police officers involved in the arrest of 25-year-old Freddie Gray on April 12.

Batts made the announcement the morning after an overnight curfew in Baltimore held for a second night. Looting, arson and street clashes with police roiled the city on Monday after Gray's funeral.

Protests over police violence spread to other major cities on Wednesday for the first time since Gray died on April 19, a reprise of demonstrations that broke out last year after killings of unarmed black men in Ferguson, Missouri, New York and elsewhere.

More than 100 people were arrested in New York overnight on Wednesday as protesters fanned out across Manhattan after a rally, briefly disrupting traffic in places.

In the mostly black city of Baltimore on Thursday morning, thousands of National Guard troops and police remained in place to maintain order and enforce a 10:00 p.m. curfew.
