Authorities have arrested a suspect wanted in connection with the bombing of a high-rise hotel in southern Thailand last year that killed three people and wounded more than 200.

Col. Komkrit Ratanachaya says nearly 100 officers raided a house in Songkhla province on Tuesday and arrested the 36-year-old suspect, Jema Wani.

He says authorities are still looking for eight other suspects in the attack.

The March 31, 2012, explosion was part of the most deadly coordinated attacks in years in Thailand's restive south. Fourteen people were killed in at least three incidents that day.

Jema was also wanted for other cases, including the shooting of a teacher and school arsons.

More than 5,000 people have been killed in the Muslim-dominated southernmost provinces of Thailand since an insurgency flared in 2004.
