Disneyland in Anaheim, California. | Paul Hiffmeyer/Disneyland Resort Muslims blocked from Disneyland trip fear they’ve been Trumped MP Stella Creasy calls on David Cameron to investigate.

A British Labour MP has called on the prime minister to intervene after a Muslim family was denied access to the U.S. at the last minute without explanation.

Stella Creasy has written to David Cameron after the family of 11 from her northeast London constituency had their travel authorization revoked at Gatwick airport's departure lounge by U.S. Homeland Security officials last Tuesday. The family, who were planning to travel to Disneyland, said they received no justification.

“It’s because of the attacks on America," Mohammad Tariq Mahmood, who was traveling with his brother and nine children, told the Guardian. "They think every Muslim poses a threat.”

Creasy said the family is now £9,000 out of pocket because the tickets' fine print says the airline is not liable if entry is refused. She wrote in the Guardian Tuesday that other U.K. Muslims have come forward with similar stories of being refused access to the U.S..

"The vacuum created by a refusal to provide any context for these decisions is fueling resentment and debate," she wrote, citing fears that U.K. Muslims are being “trumped;” a reference to Republican U.S. presidential candidate Donald Trump’s call to ban Muslims from entering America.

Creasy wants Cameron to intervene after she said she hit a "brick wall" with her own inquiries. A Downing Street spokesman said the prime minister — who has described Trump's comments as "stupid and wrong" — would respond to her letter in due course.

"Our concern should be to offer more than a critique of American Republican primary political positioning," Creasy wrote. "Because this isn’t happening in the U.S.. It’s happening on British soil, at our airports and involving our citizens and challenging their sense of place in our society too."

UK Muslim family stopped from travelling to Disneyland in US. If no good reason then this looks like Trump has won https://t.co/d91CxvKcXc — Humza Yousaf (@HumzaYousaf) December 23, 2015
