White cop tells black teen, 'I could f**king kill you'

An Illinois police officer has been recorded pinning a black teenager to the ground after the 15-year-old stepped onto his lawn to check on a friend.

Jordan Brunson's friend was sitting on the unnamed cop's front porch after allegedly being involved in a fight with other teens.

The off-duty cop can be heard in the video saying, "You are on my f***ing property, I could f***cking kill you."

"You're trespassing in my f***king yard, do you understand?"

Another teen filming the incident can be heard begging the officer to "let him go, bro".

Jordan says he wasn't asked to leave the property before he was grabbed, and was only let go when on-duty officers arrived, reports local news outlet WGN9.

The video has now been viewed more than 3.5 million times since Jordan's cousin Ann Falls posted it to her Facebook page.

"So this is what happens when you walk on someone's grass," she wrote.

"This guy is a LANSING POLICE OFFICER and our family can't get anywhere filing a report on him. I'm sick of walking while black being a problem!"

A statement released by the Lansing Police Department on Tuesday afternoon said they'd responded to a fight earlier in the day involving 30 teens.
