West Berkshire Council said that Paices Hill Green Waste and Recycling Centre will remain closed over a period of time while the police conduct their investigations into the situation.
A spokesman said: The site has suffered from vandalism and fly-tipping and commercial waste has been tipped over by the entrance gates. There are even incidents of missiles being thrown at the site but not the nuclear ones.
Police are aware of the situation and are doing work on it. We cannot say at the moment who is doing this and we will wait for the police to investigate before we can open the site again.
West Berkshires executive member for the environment and waste Geoff Findlay said: Site staff and the public were at risk following threatening and abusive behaviour.
