Police are stepping up reassurance patrols in Surrey and Sussex following the terrorist attacks in New Zealand.
Officers said they are engaging with communities of all faiths, including mosques, giving advice on how to stay safe.
At least 49 people were killed in mass shootings at two mosques in Christchurch today (March, 15).
Chief Superintendent Neil Honnor, Head of the Surrey and Sussex Police Joint Operations Command, said:
“Places of worship can use our online training package ‘ACT Awareness eLearning’ for advice on Protective Security and how to react should the worst happen.
“It can be found here.
“We also encourage everyone to be aware of the Run, Hide, Tell advice there.
“We take all forms of extremism seriously and anyone with concerns about someone becoming radicalised can get advice and support through the Prevent programme.”
