The band Lord Buffalo is cancelling a European tour after its drummer was detained by U.S. Immigration and Customs Enforcement this week.

The musician was unexpectedly detained at an airport in Dallas, the band announced on social media Wednesday.

“Our drummer, Yamal Said, who is a Mexican citizen and lawful permanent resident of the United States (green card holder) was forcibly removed from our flight to Europe,” the group said after he was detained Monday.

Lord Buffalo said it will cancel its tour to focus on helping Said.

Said is in detention and his bandmates have not been able to contact him, they said in a post on Instagram. The group has hired an immigration lawyer to secure his release. Meanwhile their touring partners, Orsak Oslo, will continue with scheduled concerts in Europe.

“We appreciate the tremendous outpouring of support from y’all today,” Lord Buffalo posted on Instagram.

A European tour poster describes the group’s music as “mud-folk psych-Americana.”
