London The British police have said they are investigating a powerful explosion which destroyed a shop and a home in the downtown of Leicester City late on Sunday evening, pointing out that there are currently no indications it was terrorist-related.
The blast happened in the central English city of Leicester. Six people were injured two of them critically. However, the cause of the explosion remains unclear.
"The incident will be the subject of a joint investigation with the fire service," the local police said on Twitter. "At this stage, there is no indication this is terrorist-related."
Fire swept through the wreckage delaying emergency services from searching for anyone trapped under the rubble, according to media reports.
Witnesses described hearing a massive explosion and then the two-floor building with a loft conversion suffered a 'pancake collapse'. A number of other buildings were damaged and homes and businesses in the area were evacuated.
University Hospitals of Leicester � one of the largest and busiest National Health Service Trusts in the UK � tweeted that four patients taken to Leicester Royal Infirmary from the scene of the explosion are in a "critical condition."
