The site is the largest of Amazon's four UK centres

A contractor is in hospital after falling through four floors at Swansea warehouse of online retailer Amazon.

The man had fallen through floorboards on the fourth floor and continued to fall through flooring until he landed on the ground floor.

The warehouse, which opened in 2008, covers an area the size of 10 football pitches and is the company's largest UK distribution centre.

Police said the Heath and Safety Executive was investigating.

The ambulance service confirmed that the man was taken to Morriston Hospital shortly after 1230 BST on Wednesday and that his injuries were not life-threatening.

An Amazon spokesman said: "An incident occurred earlier today (Wednesday), whilst work was being undertaken by external specialist contractors to construct additional product storage capacity at our fulfilment centre.

"A worker employed by the contractor suffered injuries and was taken to hospital.

"We are working with the contactor to ensure that the incident is fully investigated."
