Seven hurt in explosion at Croydon police station

Seven people have been injured in an explosion in the basement of a police station in south London.

About 50 fire fighters are tackling a resultant blaze, which began at about 11:20 today at Croydon police station.  Five people were taken to hospital, one of them said to be in a serious condition.

A police spokesman said the cause of the blast was unknown but said it was a "non-terrorist" incident.  At least some of those injured are understood to be builders carrying out work at the premises.  Cordons are in place around the building, on Park Lane.

The spokesman said the borough remains "fully operational" for police, adding "there has not been any disruption to service."  The force was unable to specify what building work has been taking place.  Health and safety investigators have been called in to investigate.
