LONDON -- A security alert that prompted a partial evacuation of London's Heathrow Airport has been resolved with no arrests, police said Thursday.

A small section of the departures area in Heathrow's Terminal 5 had been evacuated while police spoke to an individual and investigated an item at Europe's busiest airport.

Police said the issue had been resolved and the terminal was reopening.

The evacuation started at around 12:50 p.m. Heathrow Airport had confirmed the evacuation but a spokesman said flights were unaffected.

Terminal 5 is used exclusively by British Airways.
