New Orleans residents account for nearly half of the 50 people who were arrested Sunday in Baton Rouge at protests over deadly police shootings.

A list released Monday by the East Baton Rouge Parish Sherriff's office shows that 38 of the 50 people arrested at protests that began Sunday are from Louisiana. Twenty-two of them are New Orleans residents, while seven are from Baton Rouge.

A Baton Rouge police spokesman, Sgt. Don Coppola, has said that protests have become more violent as protesters from other cities arrived in Baton Rouge.

More than 180 people have been arrested at protests in Louisiana since the July 5 fatal shooting of Alton Sterling, a 37-year-old black man, during a struggle with two white Baton Rouge police officers.

Most of Sunday's arrests took place near downtown Baton Rouge, where police said they stopped a group of protesters from walking onto Interstate 110.

Authorities made more than 160 arrests in Louisiana's capital during a long hot weekend of protests over killings by police, with only one reported injury among the ranks when an officer was hit by a projectile.

Police in riot gear kept protesters from entering Interstate 110 in Baton Rouge on Sunday, thwarting a tactic activists have attempted around in the country in the aftermath of the killings of Alton Sterling in Louisiana and Philando Castile in Minnesota.

More than a thousand demonstrators left a Black Lies Matter rally in Memphis, Tennessee, and occupied a Mississippi River bridge Sunday night, temporarily halting traffic on Interstate 40. Hundreds walked onto I-264 in Portsmouth, Virginia, marooning motorists for hours.

Demonstrators failed to block highways in Atlanta, and in San Francisco in recent days.
