The Petah Tikva Magistrates Court on Wednesday extended the remand of an IDF soldier and his brother who are suspected of spray-painting racist invective in two West Bank settlements last Saturday night.

The soldier, a 19-year-old who serves in the elite unit of the Golani Brigade, will be held in custody along with his 30-year old brother for at least another 24 hours.

The two, both residents of Petah Tikva, are suspected of spray-painting graffiti inciting violence against Arabs on several Israeli-owned buses in the West Bank settlement of Emanuel. They are also suspected of puncturing the tires of a police vehicle in Karnei Shomron.

The soldier’s older brother was arrested Monday after an extensive investigation, as police claimed evidence of the incident was recorded on his cellular phone. The soldier was arrested a short while later.

Both the soldier and his brother denied the accusations made against them.

Police are investigating whether the vandalism was carried out as part of a “price tag” attack in protest of the Israeli bus company’s employment of Arab workers.

The term “price tag” is used by Jewish extremists to describe attacks typically carried out against non-Jews or their property, ostensibly as retribution for Israeli government actions deemed contrary to settler interests.

Earlier this week, the Jaffa Military Court sentenced two IDF soldiers to a five and a half month term in prison after they were accused of beating a Palestinian man while he was handcuffed.
