Police are appealing to find two men wearing high visibility jackets who were seen near a bungalow that was deliberately set on fire in Leicestershire on Sunday night.
They may be witnesses to what happened and so we would be keen to speak to them or anyone who may have seen them.
"It is likely that the person or people involved in setting this fire may have caused injuries to themselves including burn injuries so we would appeal for anyone who knows anyone who has received such injuries since Sunday night to contact us with information.
Officers were called to Aldridge Road in the early hours of Monday morning to reports of an explosion. Two officers broke into the bungalow and rescued to deaf people inside the property.
