Sri Lanka police asked for help from the public on Sunday to identify a woman suicide bomber who attacked the island’s army chief killing 10 people. The police Criminal Investigations Department said in a statement that the bomber had yet to be identified contrary to earlier claims that she was a 21-year-old pregnant woman from the island’s north. “The woman suicide cadre is believed to be in the age group of 35 to 40 years and about five feet three inches tall,” the CID said. The CID also released a pen-sketch of the woman based on forensic modeling.Logs at the army headquarters showed the bomber entered the military compound and staged the attack last month after posing as a soldier’s pregnant wife to take advantage of “maternity day” at the army hospital. However, a medical expert has said that tests showed that the woman was not pregnant, contrary to media reports at the time. Police said the bomber’s mobile phone was destroyed but they managed to recover the SIM card that has been sent abroad for analysis and to trace the calls she made and received just before the attack.
