A gym has reopened a day after a "chemical incident" left four people needing treatment at hospital. 

David Lloyd Beaconsfield, in Glory Mill Lane in Wooburn Green, had to be evacuated at around midday on Wednesday after two chemicals were mixed, causing a reaction. 

Police, firefighters and South Central Ambulance Service all descended on the scene to assist. 

Gym-goers have been told at around 1pm that the gym has now reopened. It remained shut throughout yesterday while the chemicals were removed.
