A White Plains man turned himself in Tuesday after he allegedly stabbed a teen in the neck Saturday night.

Ronnie Tineo, 20, of 86 Dekalb Ave. in White Plains, was charged with first-degree assault and criminal possession of a weapon after arriving at police headquarters with his attorney.

Tineo is accused of stabbing 17-year-old Corey Armstrong, of Port Chester, in the neck. Police said Armstrong and a friend were on East Post Road when Tineo struck him once with a knife. He is being held on $5,000 bond.

"They had previously known each other," Deputy Commissioner of Public Safety Daniel Jackson said. "They got into a verbal altercation and at one point Tineo strikes the victim with a shot."

Armstrong remains in serious but stable condition at White Plains Hospital.

Meanwhile, investigators are still searching for whoever stabbed 39-year-old Andrew Holt at Delfino Park last week. Holt was stabbed on the basketball court during a community picnic with more than 300 people in attendance.

Anyone with information regarding the Delfino Park incident is asked to call (914) 422-6111.
