In Trinidad be especially vigilant in downtown Port of Spain at night, and when travelling from Piarco Airport where gangs have been known to follow cars and attack the occupants at their destination. Five explosions in downtown Port of Spain since July 2005 have injured many people. There has been an increase in attacks at tourist sites, including Fort George and the Pitch Lake, and sometimes with the use of firearms; visitors are warned not to resist muggers and robbers who are also targeting foreigners at car parks outside places like shopping malls and restaurants. Take precautions like not wearing flashy jewellery and storing valuables in hotel safety deposit boxes. In Tobago there has recently been a spate of violent robberies against foreigners, mainly in the south west area, and crime on Tobago is a serious concern. Those staying in private villas, especially in the south west, are particularly vulnerable to violent robberies and should hire security officers; visitors are also warned against staying in villas near the Mount Irvine Golf Course area where several incidents have been reported. Use official guides to visit attractions, stay in groups in country areas, avoid isolated beaches and use taxis after dark.
