NAPLES-  Three people were injured after a gas truck explosion occurred outside a Mangrove Cafe on 5th Avenue Monday morning.

It happened just before 9:30 a.m. when Tom Smith, a Balgas Propane employee, was filling up the propane gas tanks behind Mangrove Cafe.

Willian McCauley, a Mangrove Cafe chef, and Don Kingston, a beer distributor for Tap Technology were also at the cafe at the time of the explosion.

Mangrove has been boarded up and it is still unclear whether it can be repaired or must be torn down.

Representatives with Balgas did not make themselves available for comment following the blast, which some described as "like a bomb".

Nearby restaurants were forced to be closed until around 4pm.

Smith is at Tampa's Regional Burn Center in cricitcal condition.

Kingston is at Tampa General in fair condition.

McCauley is at Naples Children's Hospital.
