A tank fittings company has been convicted of health and safety breaches over the 2005 Buncefield oil depot explosion.

Motherwell Control Systems 2003 Ltd was convicted at St Albans Crown Court. The Hertfordshire depot exploded after a massive vapour cloud ignited when 250,000 litres of petrol leaked from one of its tanks.

More than 40 people were injured and many homes and businesses were destroyed in the explosion, which measured 2.4 on the Richter scale.
