Police said they captured three of the six gunmen who held 42 people hostages for a day inside a bank they were caught robbing in this northwestern coastal city last week.

Five people were killed and 15 wounded in the botched holdup.The three suspects were arrested without incident at dawn Tuesday at the home of a relative of one suspect, said Arturo Moreno, commander of the local federal police.

Moreno identified the three as Mario Valdez Soto, 26, and Ramon Terrazas Torres of Los Mochis, and Ivan Camarena Acosta, 21, of Navojoa, Sonora state.

The three gunmen still at large included the gang's reported leader, the government news agency Notimex said. A judicial police spokesman contacted Tuesday night declined to say whether police had any leads on their whereabouts.
