Thai police say they believe they have gathered enough evidence to prosecute the person they accuse of carrying out last month's bombing at a landmark in the Thai capital that killed 20 people.

Police spokesman Prawut Thavornsiri said in a news conference Friday night that with evidence gathered from witnesses and surveillance cameras, a suspect can be charged in court. Prawut was referring to the first suspect arrested in the case several weeks ago, identified as Adem Karadeg and believed to be from Turkey. He was arrested at an apartment on the outskirts of Bangkok where police say bomb-making materials and a cache of fake passports were found.

Local media reports this past week said that Karadeg had confessed to planting the bomb at the Erawan Shrine on Aug. 17.
