Thirty-seven people were injured when a grenade exploded at a basketball court in Davao City while a circus show was being held Saturday night, police said.

The victims, whose names have yet to be listed, were all taken to the Southern Philippines Medical Center for treatment, Davao City Police director Senior Supt. Ronald dela Rosa said.

The explosion occurred around 9 p.m. inside the covered court of Brgy. Fatima in Paquibato district.

A circus show was held at the court as part of celebrations for the barangay’s fiesta on September 13, Dela Rosa said in a text message.

An unidentified person threw the grenade at an Army detachment beside the court, but the explosive bounced on the net barrier and went off at the circus audience, Dela Rosa said.

Investigators of Davao City Police Station 7, which has jurisdiction over the area, are still trying to determine the grenade thrower’s motive and identity, he said. (John Roson)
