However they are not deemed a person of interest to security agencies or police after an investigation.
A person from Afghanistan on the UK’s no-fly watchlist was flown into Birmingham as part of the evacuation of Kabul, government officials confirmed.
The individual, who was identified as being on the watchlist on arrival in the UK, was later not deemed a person of interest after investigation.
The no-fly watchlist is used to stop people coming to the UK who are thought to be a security threat.
The Home Office said the person was flagged in a “rigorous checks process”.
Someone can be placed on the no-fly watchlist due to previous serious criminal conduct as well as terrorism, the BBC’s home affairs correspondent Daniel Sandford reported.
Afghanistan is on the Covid travel red list, meaning arrivals into England must quarantine in a government-approved hotel for 10 days.
The UK is one of a number of Western countries processing people eligible for evacuation out of Afghanistan after the Taliban seized control of Kabul.
A team at Kabul airport led by the British ambassador Sir Laurie Bristow is under huge pressure to process as many people as possible ahead of a 31 August deadline.
Armed forces minister James Heappey earlier said 6,631 people had been evacuated to the UK in the past week, and that nine flights were planned for the next 24-hour period.
Those evacuated include British nationals, diplomatic staff, and Afghans eligible for relocation because they worked for the UK government in frontline roles or are otherwise considered to be at risk under a Taliban administration.
