Museum theft arrests

Four more people have been arrested in connection with a national investigation into high-value museum thefts.

A 30-year-old man and two 17-year-old boys were arrested in London, while a 37-year-old man was arrested in Hull.

All four are being held on suspicion of conspiracy to burgle.

The latest arrests come a week after 20 people were arrested following a series of dawn raids across England and Northern Ireland.

The 18 men and two women have since been bailed until January.

Chinese artefacts and rhinoceros horn were targeted in six incidents - two thefts and an attempted theft from Durham University Oriental Museum and further incidents at Gorringes Auction House in East Sussex, Norwich Castle Museum in Norfolk and the Fitzwilliam Museum in Cambridge.
