A North Platte man is in jail after he allegedly assaulted his ex-girlfriend and seriously injured her.

At around 3:05 a.m., on September 26, officers with the North Platte Police Department responded to the emergency room at Great Plains Health, where a female was receiving treatment for injuries she allegedly obtained in an assault.

Officers met with the female who stated that her ex-boyfriend, Jason Diaz, had contacted her and requested that she come to a residence in the 1800 block of West 16th Street.

The victim said she arrived at the residence and became engaged in a verbal argument with Diaz.

She told officers that, at one point, Diaz placed her in a bear hug and choked her.

She said Diaz then punched her in the eye and ribs, before grabbing a tile cutter, holding her down and cutting her hand with the blade.

Police say the victim was able to get away from Diaz and go to the hospital, where she received treatment for a severe cut to her hand, as well as multiple cuts, scrapes, and bruises.

According to police, Diaz also went to the hospital and began causing a disturbance.

Officers made contact with Diaz and determined that he was a danger to himself and others.  As a result, he was placed into protective custody at the hospital.

On October 1, Diaz was released from the hospital and taken into custody.

He was booked into the Lincoln County Detention Center and charged with felony first-degree domestic assault, use of a weapon to commit a felony and felony strangulation.
