The cause of an early morning fire in a Princes Risborough flat is being investigated.

Firefighters had to break into the first-floor flat in New Road after they were called to a blaze at 6.23am on Wednesday morning.

The fire had started in the lounge and two crews from High Wycombe and one from Aylesbury attended to put it out.

It was not immediately clear how the fire started or if it was deliberate, so the cause is currently being investigated.
