Teenagers arrested over the death of a pensioner in an alleged "rock-throwing" incident have had their bail extended for a second time.
Charlie Hilder died at Lullingstone Castle in Eynsford near Dartford in May just four days after celebrating his 40th wedding anniversary.
The two teens - aged 17 and 18 - arrested during a raid at a house in Keston, near Bromley about a month later were released on bail in June and again in July.
Police confirmed today the pair have had their bail extended again for three months.
An exact date of when they will have to answer has not been confirmed by Kent Police.
Mr Hilder, 66, suffered a heart attack while on a fishing trip at the picturesque castle on May 27, which he frequently visited.
It was reported rocks were thrown at the grandfather, who had recently marked his wedding anniversary with wife Lynne, in the moments before his death.
Mr Hilder's heartbroken family later issued a desperate appeal to help assist officers piece together what happened to cause his death.
The father-of-five had been helping two secretaries of his angling club fill the water with lucrative rainbow trout but he had stayed behind to go out on his favourite boat and fish.
Youngest daughter Sascha, 26, had made him dinner and became concerned as hours passed and calls remained unanswered so she tracked his iPhone to find he was still at the castle.
The recruitment consultant raced down from the family home in Romford, east London, and was told by police at the scene her dad had died.
Recalling the moment officers told her the devastating news, she said: "My heart just shattered."
Mr Hilder was described as "caring and always had time for anyone".
His wife, Lynne, said her husband lived his life by looking after people.
"I lost him because he was so wonderful and doing what he loved - helping people," she said.
