Nottinghamshire Police say they are responding to 'concerns' in communities, after the Woolwich terror attack in London on Wednesday.
On a statement on the police force's website, it says:
"The attack in Woolwich is a prime example of an incident which has understandably affected and unnerved people across the country, if not the world. It would be remiss of us not to respond to potential concerns in our communities.
"As always, we are doing all we can to keep you safe.
"There have been no incidents reported in Nottinghamshire as a result of Wednesday’s events in Woolwich[...]
"We will not tolerate any actions that may cause harassment or fear in our communities or compromise the safety of the public."
