A Hempstead teenager was charged Thursday with attempted murder in a machete attack last month that injured three high school students.

Evilson E. Orellana, 18, was arraigned on charges of second-degree attempted murder, second-degree assault and fourth-degree criminal possession of a weapon.

Garden City attorney Milton Grunwald, who only represented Orellana at his arraignment in First District Court in Hempstead, entered a not-guilty plea.

District Court Judge Scott Siller ordered Orellana held without bail and granted orders of protection for the victims.

New York State Park Police arrested Orellana on Wednesday night, according to Nassau County police. Park Police earlier this month said they were searching for three suspects in the May 23 attack.

A suspected MS-13 gang member, Francisco Romero, 17, of Franklin Street, Hempstead, was arrested June 6 and charged with assault, assault with intent to cause physical injury and menacing.

He was held without bail and a temporary order of protection was issued.

Orellana, along with others, physically assaulted the victims, hitting them in the back “with a knife or machete,” court papers said.

Police said the three teenage victims — Hempstead High School students — were cut and stabbed as they walked along a trail not far from the school about 3 p.m.

Randy Simons, a spokesman for the State Office of Parks, Recreation and Historic Preservation, said the three were treated at a hospital, and Park police have since increased patrols in the park.

Hempstead school officials said they also had beefed up security.

Court documents said two victims were “hit in the back with a machete,” causing lacerations.

Romero also chased the victims — as well as a fourth victim, who was not slashed or stabbed — with a tree branch, “hitting them with it and then closed his fists when the branch he was using broke,” according to court documents.

Romero told police: “The branch I used was dry and broke. When I hit the guy . . . then I just hit him with my hands. I didn’t use a knife.”
