An 18-year-old man who got into difficulty in the sea off the Essex coast has died, days after his teenage sister was killed in the same incident.
Haider Shamus and his 14-year-old sibling Malika, both from Luton, were rescued from the water near Clacton Pier on Thursday.
Malika died hours later while Haider was pronounced dead on Saturday.
Police said a 15-year-old girl, who is a relative and was pulled from the sea with the pair, is expected to recover.
Onlookers tried to save the group, with some performing CPR on the beach until ambulances arrived.
All three were treated at Colchester General Hospital, police said.
Last July, Ben Quartermaine, 15, died after getting into difficulty while swimming with a friend near Clacton Pier.
His mother and stepfather Vicky and Colin Gentry said a lack of signage in Clacton was “one of the main issues”.
They also called for better education for “all year groups in all schools, whether coastal or not”.
