PHILADELPHIA (CBS) – Philadelphia’s citywide curfew goes back into effect on Monday night as the National Guard has been deployed in the city. The curfew will last from 6 p.m. until 6 a.m. Tuesday. During this time, people may leave their homes only to go to work at essential businesses or to seek medical attention or police assistance.

This is the third straight night Philadelphia will be under a curfew.

“I am, frankly, extremely disappointed by the number of people who ignored the curfew, especially minors,” Mayor Jim Kenney said during a Monday afternoon press conference.

 

Kenney called on parents to make sure their children stay indoors and don’t break the mandatory curfew the city put in place.

“Parents, please do your part by making sure that your children, especially teens and preteens, stay home. This will go a long way to help reduce the potential of someone getting hurt, including our first responders,” Kenney said.

Police Commissioner Danielle Outlaw says the protests taking place in the city and across the country “is unlike any of us have seen.”

“We have been sitting on a powder keg for quite some time and it has burst,” Outlaw said.

Over 400 arrests have been made total and 18 police officers have been injured, ranging from chemical burns, head injuries, to broken bones.

Philadelphia now joins other cities receiving members of the National Guard. It’s the National Guard’s biggest deployment ever, even surpassing Hurricane Katrina, after communities across the country faced widespread looting, vandalism and arson over the weekend.

The National Guard will protect landmarks and serve as a backup to Philadelphia police.

“The National Guard’s mission is really to support law enforcement. They’re not law enforcement officers, they will be supporting our law enforcement,” Philadelphia Managing Director Brian Abernathy said Sunday. “In most cases, they will be protecting our assets, protecting sensitive areas allowing those officers currently doing that to redeploy into our community and neighborhoods.”

The extra patrols were needed Monday afternoon when protesters clashed with law enforcement in front of Philadelphia’s City Hall.

“We’re in the middle of one of the biggest crisis in this city’s history,” Kenney said.

Meantime, the cleanup continues in Center City’s Shopping District.

“We’ve got four teams doing graffiti removal today. We’ve removed 50 to 60 major graffiti markers,” Center City District President Paul Levy said.

Almost every business on Walnut and Chestnut Streets between 15th and 18th Streets is closed and boarded up like a big storm is about to roll through.

But Di Bruno Bros. is open, and in this time of crisis, it’s showing some brotherly love by offering on-duty police officers free lunch.

“I think it’s a wonderful idea because these people out here are serving us and working hard to protect us,” said customer Harriet Seidman.

Philadelphia city leaders have not said how long the National Guard could be here in the city.
