The National Police officially confirmed the identity of the man who bombed At-Taqwa mosque in Cirebon Police Headquarters on Friday, killing himself and injuring 30.

"DNA testing scientifically proves that Mr. X, the suicide bomber, was Muhammad Syarif," the National Police Spokesman Insp. Gen. Anton Bachrul Alam said at a press conference on Monday.

"Finger print identification found that there are 12 similar points on the bomber's finger print with Syarif's finger print on his driver's license," Anton said. Syarif, 31, of Cirebon was the son of Ibu Srimulat and Bapak Abdul Ghofur, Anton added.

On Sunday, the head of the National Police's fingerprint identification system told the Jakarta Globe that tests had confirmed the identity of the Cirebon suicide bomber as Syarif. "It was 100 percent him, no doubt," Brig. Gen Bekti Suhartono said.

Syarif leaves behind his wife, who is pregnant and understood to be expecting their child any day. His family refused to talk to the media, but neighbors told Metro TV that funeral preparations were underway.
