JERUSALEM (JTA) — Two Palestinians from eastern Jerusalem who were arrested following a Tel Aviv manhunt were released after an interrogation.

Main roads in Tel Aviv were closed for an hour on Thursday morning during a police chase that included helicopters.  Intelligence information had suggested that the two men were planning on carrying out a terrorist attack, according to Israel Police.

The men, who were arrested in the Tel Aviv suburb of Givatayim, were released following questioning by the Shin Bet security service after an investigation found no evidence that the men were planning an attack.

A Palestinian assailant from eastern Jerusalem stabbed five people in Tel Aviv last week, part of a wave of Palestinian attacks on Israelis.

Also on Thursday, an Israel Defense Forces officer fired his weapon in the air on a train leaving Haifa after other soldiers on the train identified a suspicious person and shouted “Terrorist.”

Passengers reportedly pulled the emergency brake, allowing police officers to board the train. Police did not find any suspicious persons on the train.
