A British Airways plane bound for Gatwick has been forced to return to northern Greece after suffering an apparent electrical fault.
The Boeing 737, carrying 95 passengers, flew back to Thessaloniki late on Monday afternoon after pilots noticed a possible problem.
"There was a cockpit indication shortly after take-off. As a precaution it returned to Thessaloniki," BA said.
Passengers from BA 2643 were being put up in a hotel overnight.
The plane was later being inspected to try and find the cause of the problem.
A BA spokesman added: "These things happen, unfortunately. The pilots err on the side of caution every time, which is the right thing to do."
