Violent groups attacked Chicago police vehicles in at least two incidents over the holiday weekend, injuring one officer.

In the first incident on Saturday night, a rowdy crowd attacked Chicago police squad cars. The crowd kicked the vehicle doors, jumped on the hoods, and punched the windshields, according to WBBM-TV.

Chicago police said an officer was traveling in a marked patrol car in the area when an object struck the vehicle, shattering the windshield. The officer was taken to a local hospital and treated for minor injuries.

Additional officers were called to the scene for backup. No arrests were made.

A second attack happened early Monday morning, when fireworks were shot at Chicago police vehicles.

Towhnall senior writer Julio Rosas, who was in Chicago reporting on violence over Independence Day weekend, shared video of a crowd launching fireworks at cop cars as they slowly backed away at an intersection.

Individuals can bee seen kicking the police vehicle in the video as it retreats.

\u201cTowards the end of the video, you can see a firework land on the hood of a CPD vehicle. The vehicle sustained damage, including: broken headlights, windshield shattered, and damage to the hood. Officers were inside the vehicle.\u201d

There have been no reported arrests from the second incident and no officers were harmed.

Chicago police increased their presence in city neighborhoods for an expected surge in violence over the long weekend. At least 54 people were shot, seven fatally, over 4th of July holiday weekend, WLS-TV reported.

There were 22 people shot on Friday alone, four of them killed. Chicago Police Superintendent David Brown pleaded with parents to keep track of their children amid the violence.

"There's no reason why everyone can't enjoy the holiday and every event safely. Parents, please, please know where your children are," Brown said, according to Fox News. "Don't leave them to government to be the parents of your kids. We need you, parents, please, to help us make sure your young people are safe."

Victims of the deadly shootings include a 24-year-old woman who was caught in the crossfire between two gunmen and a 26-year-old man who was killed in a drive-by shooting while he was riding a bike.

The youngest victim of the weekend violence was a 10-year-old boy who was wounded by bullets inside of his own home. The boy was sitting inside his bedroom when gunfire struck his house, hitting him in the buttocks and in an ankle. He was taken to the University of Chicago Comers Children's Hospital in good condition, police said.

Last year, 19 people were killed and more than 100 people were shot in Chicago while the country celebrated Independence Day.
