PORTLAND, Ore. -- A man allegedly attacked several people at Essex Park in southeast Portland on Tuesday afternoon.

Nelson Elias Epel, 20, is facing multiple charges, including felony assault and robbery. Bail for Epel is set at $287,500.

According to court documents, two women told police they were at the park with their children when Epel, a stranger to both women, approached them at around 5:45 p.m. Tuesday.

One of the women said Epel said, "Have a nice day," to which she responded, "You, too."

"What did you say, bitch?" Epel replied. He dumped the contents of her water bottle on her head before punching her in the face. He then punched the other woman in the face twice.

The two women tried to run away with their children but Epel chased them to the tennis courts. They ran past another woman who tried to call 911 on her cellphone, but Epel hit her with a tennis racket and stole her phone.

Two men intervened to help stop the attack. One of the men, Justin Hemphill, said he was sitting at a bench in the park when one of the women came over and said she was being threatened.

“I just grabbed him by the waist and threw him around and we got in a fight,” Hemphill said. “I knocked my head going over that wall so I don’t remember much of it.”

One man had cuts on his face, a swollen ear and bruised ribs. Hemphill was left with a broken nose and lacerated lip.

“I think I got kicked or hit with tennis racket,” Hemphill said. “My wife said I got hit once. The inside of my mouth is all black and blue.”

By the time officers arrived, Epel had fled the scene. He was found in the area and positively identified by one of the victims.
