A man believe to be linked to a series of "price tag" attacks against Israeli peace activists has been continuously emailing death threats to leading Peace Now activists, just a week after being released to house arrest.

The man, 21, was indicted less than two weeks ago for incitement for racism and vandalism of property, after had admitted to spraying graffiti in several locations in and around Jerusalem, reading "price tag" and "death to the Arabs."

"Price Tag," is the name given by extremists to activities against Palestinians, peace activists or security forces in response to what are considered to be actions against the settlements or illegal outposts in the West Bank.

He was subsequently released to house arrest and forced to wear an electronic bracelet.

However, police officials have indicated that the man had continued his "price tag" activities from within his Jerusalem home, sending death threats to Peace Now management, without even bothering to conceal his name.

Peace Now chief Yaniv Oppenheimer said that "at about 3:30 I suddenly received a threatening email." That message, the Peace Now activist said, was "'Today you die.' Then I spoke with the others and found out that I was only the last to receive such an email. Hagit [Ofran] got one and others too."

The suspect sent death threats to all of the Peace Now activists, only differently phrased. To Ofran, the group's head of settlement tracking, he wrote "Hagit Ofran, R.I.P.," while to the head of Jerusalem activities Danielle Blumenstyk he wrote "I'll kill you. The end is near."

The man, the name of whom is still under gag order, is linked to an attack on Ofran's home earlier this month, in which swastikas graffiti slogans were prayed on her Jerusalem home.

The graffiti warned: "Hagit Ogran, Rabin is waiting for you", referring to the assassination of former Prime Minister Yitzhak Rabin, by a right wing-activist.
