DHAKA, Sept. 6 (Xinhua) -- The Bangladesh police cordoned off a building in the capital's diplomatic enclave Gulshan on Tuesday, where militants were suspected of being holed up.
Additional Commissioner Md Shahabuddin Qureshi told reporters that they cordoned off the multi-story building on information that three suspicious persons carrying bags entered the building forcibly.
"We're not sure yet whether they are thieves or militants," he said.
Hundreds of policemen stood guard outside the building from where two bags have been recovered.
"Our bomb disposal experts will examine the bags," he said adding after that "we could understand the real situation."
Security has been tightened in Bangladesh after militants attacked a Spanish cafe in Dhaka's Gulshan on July 1, which left 22 people, mostly foreigners, dead.
