WATCH: White woman rips away sign from BLM protester -- then cries like a baby to cop when she gets punched

A white woman was caught on camera ripping away a sign from a Black Lives Matter protester -- and then crying to a police officer when the woman who was holding the sign punched her in retaliation.

A video showed the woman arguing with black demonstrators in Minneapolis who were protesting the fatal shooting of Thurman Blevins, an armed black man who was killed while trying to run away from police. The woman apparently had been blocked by the protesters and complained that she just wanted to go home.

A few seconds into the video, the white woman rips away a female protester's sign that featured a portrait of Blevins -- and the protester responded by punching her.

The video then shows the woman walking with a Minneapolis police officer and loudly crying to him about what happened to her. But Minneapolis police said no formal complaint was made.

As Minnesota's Star Tribune reports, demonstrators descended on Hennepin County Government Center this week to protest against the decision to not charge the officers involved in the Blevins shooting.
