JAKARTA, Indonesia – An unidentified gunman with alleged ties to Abu Roban's terrorist group shot and killed a police officer in front of a hospital in Ciputat, Tangerang early Wednesday (August 7th), local media reported.

Dwiyatna was headed to work when he was shot in the back of the head around 5am, Jakarta Police spokesman Rikwanto said.

"Witnesses are now being questioned at the Cilandak Police station, and the South Jakarta Police and Ciputat Police are jointly investigating this," The Jakarta Globe quoted him as saying.

It is at least the third shooting of a police officer in the last 30 days, according to The Jakarta Post.

According to the Globe, Rikwanto said the perpetrators of the most recent shooting may have also been behind the July 27th attack of Patah Saktiyono, of the Central Jakarta Police's traffic division.
