Andra Wisnu, Jakarta – Dozens of activists gathered Thursday at Jakarta Police headquarters, demanding that the police finish their investigation of the Situ Gintung case they reported a month ago.

"We have not received a single update on the case so far," Asfinawati, the activists' spokesperson, said. "We want the police to give us an update on their investigation as we found indications that a crime had been committed," she said.

Situ Gintung, a dam in Cirendeu, Ciputat district, Tangerang, Banten, burst on the morning of March 27, killing 100 people, injuring 135 and displacing hundreds of residents who lived near the dam. Hundreds more buildings and homes were destroyed.

The government has promised to give compensation for the resident's losses.

Many activists blamed the Tangerang government and the Ministry of Public Works for the incident, saying that they failed to prevent the dam from bursting.

In response, police spokesperson Adj. Sr. Comr. Chrysnanda told the protesters to be patient and urged them to stop looking for people to blame.
