VIDEO footage has captured a heavy police presence at Redbridge Hollow traveller site in Oxford last night.
The footage, sent in to the Oxford Mail, shows a number of stationary police vehicles, including cars and vans, with blue flashing lights.
One witness said they saw 'at least 25 police vehicles, dog vans and armed officers'.
They added that police helicopters were out most of the night, until at least 3am.
A spokesperson for Thames Valley Police said the force was called to reports of a large-scale public disorder at just after 9pm.
One man, aged 30, from Oxford, has been arrested on suspicion of threatening to damage or destroy property and remains in police custody at this time.
A murder investigation was launched last month, while a Home Office post-mortem examination concluded that a man died as a result of a head injury at Redbridge Hollow.
The body of a 33-year-old man, named online as Anthony Joyce, was discovered just after 11.50am on Saturday, June 27.
Mr Joyce's wife Margaret wrote on Facebook a tribute to her partner.
She said: "God, my lovely husband Anthony, my old heart is broken.
"I will never forget you I promise you, I have a pain that will never go away but I will get justice for you.
"It is just terrible – Anthony was harmless, he did not deserve that."
Speaking after the investigation was launched, senior investigating officer Detective Chief Inspector Stuart Bosley said police would leave 'no stone unturned' in finding out what happened.
