A seven-year-old boy has died a week after an incident off the Essex coast in which his teenage cousin and her mother died as they tried to rescue him.

Musa Ahmed was being treated for life-threatening injuries after being pulled from the sea near West Mersea beach on 22 July.

Shelina Rahman, 41, and her 15-year-old daughter Sameeha died after the incident.

In a statement, the boy’s family said: “We would like to thank the Royal London hospital intensive care unit team of doctors and nurses who demonstrated outstanding care and dignity for whilst we have been at the hospital.

“We would also like to thank the whole community for their support and prayers.

“We would appreciate privacy during this very difficult time.”
