Police have renewed their appeal for information after a man died of a heart attack following a possible altercation at a castle in Kent.

Officers were called at 5.21pm on Thursday 28 May to reports of a disturbance in the grounds of Lullingstone Castle.

66-year-old Charlie Hilder from Romford, Essex was pronounced dead at the scene.

It is reported Mr Hilder may have been involved in an altercation with two boys or teenagers near to a lake within the grounds, prior to his death.

A post-mortem examination, carried out on Monday, has concluded Mr Hilder died from a heart attack but officers are continuing to investigate the wider circumstances.

It is understood that, at around 5pm, a brief dispute took place, during which items were allegedly thrown towards Mr Hilder.

Several minutes later a further verbal argument took place between the boys and Mr Hilder in a car park, which is by the lake and near the castle gate.

After the boys had left, at around 5.50pm Mr Hilder collapsed and later died.

Detectives would like to speak with the two boys, or anyone who saw them in the area.

They are understood to be white and aged between 11 and 18. At the time they were wearing dark t-shirts and lighter coloured shorts.

One of them may have been carrying a fishing rod.

We are seeking to obtain any information that can help us establish the full circumstances leading up to Mr Hilder’s death. We have now established that a man and a woman, aged around 20, were sunbathing or picnicking in the field near to the car park at around 5pm and would urge them to contact us at their earliest opportunity. We would also like to obtain any video that may have been recorded by motorists or cyclists who travelled along Castle Road or Shoreham Road, between 12pm and 7pm on 28 May.
