'A covert Shin Bet agent is operating in Mercaz Harav Yeshiva'

An announcement posted and circulated in Mercaz Harav Yeshiva in Jerusalem in recent days warns students that a Shin Bet agent, masquerading as a friend of one of the eight students killed by a terrorist in the school two weeks ago, has been frequenting the school grounds and trying to glean information from students, Army Radio reported Thursday. "Keep your eyes open and avoid unnecessary conversations," says the announcement, which asserts that the parents of one student spoke to the suspicious-looking man and understood that he was trying to obtain information about possible revenge measures.
