Massive Attack says its members are detained and questioned by Singapore police after a concert where performers displayed a Palestinian flag. The band says police isolated members, separately questioned them, and searched hotel rooms. It also says passports were temporarily confiscated. Multiple outlets report that Singapore authorities are investigating possible licensing or permit breaches related to the public display of a foreign national emblem. Singapore’s Infocomm Media Development Authority (IMDA) is cited as having issued warnings and deciding not to grant any future performance applications from the band in Singapore. Separate reports state that two core members are banned from reentering the country and that authorities issue a stern warning. Coverage also indicates Singapore police and IMDA communicated the outcome after the incident, following the concert’s end. The outlets agree the decision to bar the band’s members is linked to the Palestinian flag display, while the band describes the episode from its side as detention, questioning, and passport seizure, along with searches at their accommodation. The matter is framed by Singapore officials as a compliance issue under local rules for public display of foreign national emblems.
