COUNTER Terrorism Policing has launched a campaign to help keep crowded places secure over Christmas.

This comes after an attack on London Bridge which cost the lives of two people.

Sussex Police officers are calling on people in busy towns and cities to remain vigilant and report any concerns to staff or security.

People can also report – in confidence– to the police at gov.uk/ACT.

This annual campaign asks everyone to be "the extra eyes and ears of the police" so that we can "work together to tackle terrorism".

Assistant Chief Constable Dave Miller, head of the Surrey and Sussex police operations command, said: "We are asking everyone out and about enjoying the season to put security at the top of their festive list.

"The chances of any one person being caught up in a terrorist incident are low. But sadly, as we saw in 2017 and even at the end of last month, attacks can be carried out anywhere and anytime.

"The national threat level remains Substantial, meaning an attack is likely, so we need to remain vigilant.

"Our message to people across Surrey and Sussex is not to worry that you might be wasting our time.

"If you see something that doesn’t look right – ACT. Report it either to local security or staff - or to police at gov.uk/ACT or via 999 if it is clearly an emergency – and let us check it out."

The campaign is being supported by police forces across the country.

A Sussex Police spokesman added: "We are also asking for businesses and other organisations that operate in crowded places across our region to support us by displaying our messages.

"We are particularly encouraging members of the public visiting busy towns and cities, or staff who work in crowded places, to be aware of our message."
