Lothian and Borders Police are appealing for witnesses following a suspicious incident in West Lothian.
Emergency services responded to an address in Dixon Court, Whitburn around 10.50pm yesterday (Wednesday) following reports of an explosion.
A full investigation was carried out in the area and a length of live electrical cable was found to have been tampered with.
Officers believe someone tried to steal the cabling, resulting in a flash of light and an electrical surge.
Anyone who remembers seeing anything suspicious in the area last night is now asked to come forward.
Inspector Ian Moffat said: “We are still trying to establish the full circumstances of this incident. However, it appears an attempt has been made to cut through the electrical cable to remove it.
“Whoever was responsible put their life in serious risk and there is potential that they may have suffered electrical burns or other injuries.
“We are keen to trace those who were at the site last night and anyone who can help identify them is asked to contact police immediately.
“Aside from the obvious cost implications, metal theft can also make an object unsafe for use and put the public in danger.
“Those who would like information on protecting their property from metal thieves can contact their local policing team or visit the Lothian and Borders Police website at www.lbp.police.uk”
Anyone with any information can contact Lothian and Borders Police on 0131 311 3131, or the charity Crimestoppers in confidence and complete anonymity on 0800 555 111.
