Around 130 police officers from Lancashire have been deployed to London and Scotland to help provide additional security around President Trump's visit to the UK.
Police officers were sent to assist in the operation on Wednesday along with hundreds of other officers from across England and Wales.
A police spokesman said: "Police forces are working together on a significant security operation supporting the Presidential visit to the UK. All police forces in England and Wales are providing officers and resources to assist with the operations in areas hosting the visit.
"In Lancashire we are working to balance support for the Presidential visit with responding to calls for help from the public and minimising the impact on policing our communities in what remains an extremely busy period."
