A group of travellers have occupied an empty industrial building.

The group – consisting of around 10 caravans as well as cars and vans – is believed to have arrived at the unit on Avenue One in Letchworth GC on April 30.

The site was previously home to BT Engage.

A spokesman for Hertfordshire Constabulary said officers are aware of the situation but it is up to the owner to evict people from their land.

Occupying an industrial unit is a civil offence under common law and the travallers can only be forced off the site if the owner obtains an interim possession order (IPO) giving occupiers 24 hours to leave or face breaking the law.

Squatters Right, as the law is commonly known, was changed in 2012 making it illegal for people to occupy empty residential buildings, however this does not include non-residential buildings, like the former BT Engage building.
