LONDON (AFP) – Counter-terrorism officers have arrested three men for alleged terrorist funding, just days after a BA worker was detained on suspicion of the same offence, police said.

Officers arrested the suspects in Berkshire in raids early Wednesday and took them for questioning at a London police station.

"Three men were arrested... for an alleged offence of terrorist fund raising," said a spokesman from the Metropolitan Police.

"The men aged 31, 32 and 43 were arrested at separate residential premises."

"Searches are being carried out in connection with the arrests," said the spokesman.

It came after a 30-year-old British Airways worker was detained at one of the airline's offices in Newcastle last Thursday for a similar offence.

"An employee was arrested at our Newcastle office last week," said an airline spokesman.

"We take matters relating to security extremely seriously and as a responsible company always cooperate fully with the police."

Detectives were granted more time to question the man, who is detained in London, during a court hearing on Saturday.
