Kathmandu, May 20 (IANS): Following the arrest of a Briton for participating in an anti-Constitution protest in Kathmandu, Britain has urged its citizens not to get involved in ongoing political activities in Nepal.

"If you are involved in any political activities in Nepal, you may be liable to penalties, including deportation and/or a fine," said the British government in a travel advisory issued for its citizens.

Nepal Police on Monday arrested British national Martin Travers for participating in an anti-Constitution protest carried out by Madhesi and Janajati activists in Kathmandu.

After completing the investigation, the police handed him over to the British Embassy in Kathmandu.

Earlier, Nepal had deported Canadian national Robert Penner for supporting the ethnic movement on Twitter.

Disagreements arising from Nepal's new constitution have led to protests, rallies and strikes occurring frequently across the country, said the travel advisory issued by Britain's Foreign and Commonwealth Office.

It advised its citizens to monitor the state media and follow the advice of the local authorities and tour operators. 

"British government officials in Nepal may sometimes defer travel on official business, depending on the security situation at the time. Transport and public services may be disrupted at short notice," the advisory added.
