Police: Suspects posted video of themselves attacking elderly woman. And that led to their arrest.

Minnesota police arrested two men after the pair allegedly posted a video on Facebook that reportedly showed them attacking and robbing an elderly woman earlier this month, according to WCCO-TV.

The video, which went viral on social media, assisted police who used the images to search the cameras located inside and outside a transit center in south Minneapolis where the attack occurred.

Wesley Martin, 20, allegedly robbed the woman, and police believe Deondre Jackson, 20, recorded the attack on his phone.

What happened?

A man wearing a blue jacket is seen taking a bottle of liquor from the inside of the victim's jacket.

He then held her down while he ran his hands across her stomach, legs, and bottom, as she cried for help, according to court documents.

Another man used his phone to narrate and record the attack.

"That lady like a 100 years old," someone can be heard saying in the video.

Finally, another man dressed in camouflage jumped in, started punching the suspects, and helped stop the attack.

What did the police say?

Police credit the social media video and cameras at the scene for leading them to the suspects.

“Because of that video, we were able to go and look at our cameras and be able to better identify some of the individuals,” Metro Transit public information officer Howie Padilla told WCCO.

Police charged both Martin and Jackson with first-degree aggravated robbery.

“These arrests, these charges, they are an absolute testimony to those security measures that we talk about all the time,” Padilla said.
