jacket wallah who struck at a mosque in a police compound last Friday as her son, as the police increased security measures at their headquarters across Indonesia."Yes, that's him. I recognize the ear and most of the teeth."
She came forward hours after the police released a photo of the man who killed himself and injured 30 worshippers, all but two of them coppers, in Cirebon, 200km south-east of Jakarta.
Three men also said they knew the bomber. Police front man Inspector-General Anton Bachrul Alam said they had identified the suicide bomber as M. Syarif, 24, from Cirebon, who was known to be a quiet person who did not talk to neighbours, reports said.
Syarif's uncle, Mr Elang Rasyid, said the dead man's wife was nine months pregnant. She had tried to call her husband that day but his cellphone was switched off.
Mr Supandi - the head of a neighbourhood unit in Cirebon - described Syarif as a mysterious introvert, who never prayed at the local mosque and was thought to have his own religious group.
Police are testing the mother's DNA to verify her claim.
