The passengers were later flown to their destination on a replacement flight, while the plane was inspected.
A BA spokeswoman said: "Safety is always our first priority, and the aircraft diverted purely as a precaution."

British Airways has decided to stop flying over war-torn Iraq.
The decision came after America's Federal Aviation Administration (FAA) today issued a Notice to Airmen (Notam) "restricting US operators from flying in the airspace above Iraq due to the hazardous situation created by the armed conflict".
Another UK carrier, Virgin Atlantic Airways, had already stopped flying over Iraq, while other airlines which are bypassing the troubled Middle East country include Air France and Dubai-based Emirates.
BA had been continuing to use Iraqi airspace in recent days while reviewing its position on a daily basis.
BA uses Iraq airspace to reach such destinations as Dubai and Doha in Oman.

Customers with tickets on those routes are being offered a range of options including a full refund and the ability to rebook their flights to a later date.
British Airways' boss said the airline will continue to fly over Iraq, despite other European firms diverting their planes amid heightened fears following the downing of Malaysia Airlines flight MH17.
Willie Walsh, chief executive of BA's owners International Airlines Group, told the Financial Times (£) he considered the airspace safe.
"We fly over Iraq because we consider it safe - if we thought Iraq was unsafe we would not fly over Iraq," he said.
BA had decided not to fly over Ukraine prior to the MH17 crisis.
British Airways is to be sued for damages over claims one of its pilots sexually abused children in African schools and orphanages.
Lawyers representing 16 young girls and women who claim First Officer Simon Wood assaulted them said the airline bears responsibility because he carried out the alleged attacks while on stopovers.
An inquest is due to be held into the death of Wood, 54, who was struck by a train in August while awaiting a court appearance accused of indecently assaulting a young girl and making indecent images of children.
Law firm Leigh Day said Wood allegedly molested youngsters during stopovers in Kenya, Uganda and Tanzania while flying for British Airways. Some of their clients are aged just eight.
