Police in the resort town Nha Trang are investigating a petrol bomb attack on the guard station of a major hotel and shopping complex early on Saturday.
The brazen attack has stirred a town that's been known for years for its tight security.
Nguyen Van Ngan, Nha Trang's Chief of Police, said the Hoan Cau Khanh Hoa Company, which owns Nha Trang Center has filed a petition to the authorities.
According to initial reports, two men traveling on a motorbike lit and threw the petrol-filled glass bottle into the shelter staffed by the center’s guards on Ly Tu Trong Street at 1:25 a.m.
The center’s front gate is on Tran Phu Street.
The attack caused no casualties or significant damage, the police said.
But the leaders of Hoan Cau Khanh Hoa say the attack represents a threat to public security.
“The act was reckless, extremely dangerous and severely affected the security at Nha Trang Center,” they said in a public statement.
Camera images showed that many street lights illuminated the area at the time of the attack, making it seem particularly brazen.
Guards at the center said the two men drove around the center before throwing the Molotov cocktail.
Nguyen Van Trung, the center's chief of security, said they argued with a taxi driver the previous night for parking in front of the mall's entrance.
Locals and tourists have expressed concerns about a resurgence of underworld gangs that were very active before a crackdown several years ago.
Nha Trang has been a top destination for Russian tourists to Vietnam since Cam Ranh Airport, some 30 kilometers from Nha Trang, was upgraded to serve as an international airport in 2009.
The airport, built by the US and used as a military air base during the Vietnam War, continued to be used for military purposes until 2004.
