T

he police finally found the gas leakage location that caused a explosion at a house in Medan, killing three people, after an investigation that lasted for two weeks.

Medan City Police chief Sr. Comr. Jean Calvijn Simanjuntak said the police worked with building construction experts and skilled workers when looking for the leakage point. He said that the experts had to dig under the destroyed house to find the exact location.

He added that three to four days were needed to dig under the house, something that required extreme caution to keep the house from further collapse.

“Finally, we found the explosion spot. This finding confirmed that the explosion was caused by gas leakage and no other reason,” he said on Saturday.

Calvijn added that after finding the gas leakage point, the team is studying the chain of events that lead to the explosion and that they would be revealed soon.

“We will present the process soon,” he said.
