A policeman accidentally brought home one of the two terrorists who committed the shooting attack in Tel Aviv on Wednesday.

Four Israelis were killed and six others were wounded after two Palestinian gunmen opened fire at passersby at Sarona Market, an upscale food and retail complex in central Tel Aviv.

The policeman, the son-in-law of former Police Commissioner Assaf Hefetz, was with his family near the site of the attack and rushed with them home, which is walking distance from Sarona.

The policeman's wife recounted their encounter with the terrorist on Channel 2 on Thursday. "We were sitting on the bench in front of the Cinematheque when we heard shots," she said. "After a few seconds we saw people running in our direction," she recalled. "When we understood what was happening we ran toward our apartment just across the way. We entered the apartment along with another man. He simply ran in with us. I asked him who he was. He didn't answer. He just asked for water."

The wife said the man sat down and looked totally afraid. "He received a cup of water," she said. "We tried talking with him. He didn't speak." She said her family asked him if he understood English or Hebrew, but he remained silent.

"My husband entered with us but took his weapon and ran out. We didn't suspect anything," she said. "He looked just like someone from the scene in shock, like us. He didn't say a word. He just mumbled. It did not look like he was in a mood to talk. He just looked in shock."

She said that when her husband went to the scene of the attack and saw that the first terrorist was dressed like the man he had left at home, he realized immediately what was going on and quickly ran home, came inside, put the terrorist on the floor and handcuffed him.

"We opened the window, called on the forces below," she said. Her husband stayed on the terrorist to keep him from trying to escape.

While arresting him, one of the policemen called in to help entered the home with his weapon drawn. When he saw that the terrorist was already captured, he returned his weapon to its sheath, at which point it discharged a bullet. "My husband was wounded by shrapnel," the policeman's wife said.

"We were very lucky that he was so much in shock and of course unarmed," she added. "The biggest fortune was that my husband realized very quickly who was home and returned. That was my husband's biggest fear – that he would come home and everyone would be dead."

Meanwhile, the police and the Shin Bet security service have been investigating an additional object from the scene of the attack that has concerned the investigative team and indicates that the terrorists had planned a much deadlier attack. That object was transferred for further examination in order to determine the extent of the danger it posed.
