Police say five people have been arrested after an incident at Llanelli's Stradey Park Hotel, which is set to house asylum seekers. Dyfed Powys Police has appealed for "calm and co-operation" after what is described as a "concerning escalation of behaviour by some protesters". Last night, officers say that a number of people trespassed onto the grounds of the hotel and "conducted themselves in an intimidating manner". And on Monday, police received a report that criminal damage had been caused to a contractor's vehicle whilst he was driving away from the premises, resulting in a man being arrested and charged. The four-star hotel is due to house more than 200 asylum seekers as part of a Home Office proposal. The plans have met with outcry from locals and an unsuccessful High Court challenge by Carmarthenshire Council to block it, on the grounds of the hotel undergoing a "proposed material change of use without planning permission".

As a result , a Section 60AA order (Criminal Justice and Public Order Act 1994) has been put in place. This provides officers with the power to require a person to remove any item which the officer believes is being worn wholly or mainly for the purposes of concealing their identity. The order applies to the area of Stradey Park Hotel, Pentrepoeth Road and the B4309 running through Furnace. "We will always seek to facilitate peaceful protest, while balancing it with the rights of others, keeping the public safe and preventing crime and disorder. Where an offence is committed, we will take all reasonable and proportionate steps to bring offenders to justice.
