Five young tourists drowned at Himchari beach in Cox's Bazar after a strong current swept them away while they were bathing near the Himchari Museum on the Marine Drive, police said, with the last body recovered on Thursday evening.

Ramu police chief AK Fazlul Haq said local people spotted the body of SM Nafisur Rahman Nibir near Bhangar Mor on Kolatali beach at about 7:00pm on Thursday. Beach workers and lifeguards were alerted and officers brought the body ashore, nearly 27 hours after Nibir went missing on Wednesday afternoon.

The body of another member of the group, Md Harun, 20, was found earlier on Thursday at the Sagar Nibas area of Himchari. Police and fire service officials said Harun, from the Bayezid area of Chattogram, was recovered after local people saw him floating in with the tide.

Three others were recovered within hours of Wednesday's accident: Al Mahibul Ibne Mokarem Rohan, 24, and Saibul Haq Jisan, 23, both from Diabari in Uttara, Dhaka, and Akash, 21, from Chattogram's Bayezid. One more tourist was pulled from the water alive and taken to Cox's Bazar Sadar Hospital in a critical condition, said Dolon Acharya, senior station officer of Cox's Bazar Fire Service and Civil Defence.

According to police, two groups were at the beach that afternoon: seven young men from Uttara in Dhaka and five from Bayezid in Chattogram. When one of the Chattogram group was seen going under, the others went into the water to help. None of them knew how to swim, and five were swept away by the current, bdnews24.com reported, citing police.

The group had arrived in Cox's Bazar around 11:30am on Wednesday and checked into a resort near the Himchari Museum on Pechar Dwip around 1:00pm, Ramu Upazila Nirbahi Officer Md Zillur Rahman said. They went into the sea at about 4:00pm.

Himchari lies about nine kilometres south of Cox's Bazar town on the Marine Drive, where the beach narrows between the hills of Himchari National Park and the Bay of Bengal. The accident came in the middle of the Durga Puja holidays, when more than 300,000 tourists were in Cox's Bazar and hotels and resorts across the town were reported to be full.

Imtiaz Ahmed, regional director of the private lifeguard company Sea-Safe, told Prothom Alo that 27 lifeguards cover the roughly five kilometres between Kolatali and Laboni Point, and that there are not enough staff for the long stretch of coast running south through Dariyanagar, Himchari, Patuartek, Inani and Teknaf. He said at least 20 hidden channels have formed off Kolatali, Sugandha and Laboni, including the Himchari-Dariyanagar stretch, and that many bathers ignore the red flags put up at dangerous points.

Zillur Rahman said the beach where the group entered the water is largely secluded, and that local fishermen had repeatedly warned tourists not to go in. The local administration is now working to raise awareness in the area, he added.

It is still unclear whether any warning sign or lifeguard was posted at the spot where the five entered the water, and police have not said whether a case has been filed over the deaths. Early reports also differed on the size and make-up of the group: Prothom Alo described a single group of 12 from Dhaka, while police later spoke of two groups from Dhaka and Chattogram.

The bodies were kept at the Himchari police outpost before being sent to the morgue at Cox's Bazar Sadar Hospital after legal formalities, and police said the usual legal process was under way. Relatives told The Business Standard that Jisan was a computer science student at the Islamic University of Technology and that Rohan was studying for a BBA at the Bangladesh University of Professionals. Nibir was a third-year computer science student at North South University.

The drownings have renewed attention on safety along the southern end of Cox's Bazar's beach, which draws large crowds in the holiday season but has far fewer lifeguards than the main Laboni-Kolatali stretch. On 27 September, a tourist drowned at Laboni Point after being swept away by the sea, according to Prothom Alo. The district administration has not announced any new restriction on bathing, and the holiday season continues.
