BENGHAZI, Libya (WKOW) -- Four people have been arrested in connection with the attack on a U.S. consulate in Libya.

The president of the parliament's top aide told CNN early Friday four were arrested in connection with the attack, but they are not directly tied to the attacks that killed U.S. Ambassador to Libya Christopher Stevens and three other Americans. The people in custody were not identified and CNN was not given details of the allegations against them.

The U.S. consulate in Benghazi was attacked Tuesday. Along with Stevens, the Americans killed have been identified as Tyrone Woods and Glen Doherty, both former Navy SEALs, and computer expert Sean Smith.

On Thursday, we learned at least one person had been arrested and three or four others were being pursued. The original arrest was made in Benghazi and that person and those being sought were all Libyans, according to the Libyan Prime Minister. "The evidence itself is based on mostly pictures that were taken around the compound at that time, and also through some witnesses," he said.
