Fire officers are trying to determine the cause of a fire which destroyed a portion of a building in Tunapuna that housed Caps Bar yesterday.

The building was located at the corner of Picton Street and the Eastern Main Road.

Residents said they heard a loud explosion around 6.18 am before the fire started.

Fire appliances from the Tunapuna and San Juan Fire Stations responded to the blaze and firefighters were able to contain the blaze to a room located on the southwestern side of the building, which is closest to the main road.

Fire officials said while the cause of the fire is yet to be determined, the operator of the bar, Saleem Sammi was the only person at the bar when the fire broke out. He was not injured in the blaze.

Fire officials said so far they were able to locate the owner of the building, Silvia Ramlosingh.

Investigations are ongoing.
