A bus driver in England has been suspended for refusing to drive a bus adorned with LGBTQ-pride-themed numbers, a report said.

The driver allegedly got on the bus in Norwich and told passengers, “this bus promotes homosexuality and I refuse to drive it,” according to the BBC.

The bus featured rainbow-colored neon letters above the front windshield that identify the bus by number.

The company that operates the bus, Go East Anglia, told the BBC that the driver had been suspended after passengers complained and that an investigation was ongoing.

The company said in a statement that it “prides itself on values that support diversity and inclusion and has been a champion of Norwich Pride since 2017.”

“We particularly want all customers of whatever background or sexual orientation to feel comfortable on our services,” they added.
