Gunmen on a motorcycle shot dead two policemen near the Indonesian capital, police said Saturday.
One of the officers was riding a motorcycle when two attackers approached and shot him late Friday in Tangerang, just west of Jakarta, city police spokesman Rikwanto said.
A group of policemen in a minivan gave chase but crashed into a gutter, and one of the gunmen shot dead the driver, Rikwanto said.
The attackers managed to escape after stealing another motorcycle.
It was a second attack targeting police this month.
On August 7, a gunman also killed an officer while he was riding a motorcycle in Tangerang.
In July, a traffic police officer was killed in another drive-by shooting, also in Tangerang.
Jakarta police chief Inspector General Putut Eko Bayuseno said the attackers were suspected to have links to a terrorist group, the Kompas.com news website reported.
“The modus operandi is similar” to the previous attacks, Bayuseno was quoted as saying.
Indonesian police have killed more than 70 terrorism suspects and arrested hundreds of others since the 2002 Bali bombings, in which 202 were killed, mostly foreign tourists.
Analysts said local militants have increasingly targeted the police in lower-profile attacks in recent years, veering away from attacking Western interests.
