Three men were taken to the hospital in Alexandria, Virginia, Monday after suffering electrical shocks when they came into contact with a power line at a construction site, authorities said.

Two of the men have life-threatening injuries, police said.

It happened Monday at 6336 Stevenson Ave. at 11:08 a.m. The men are site workers, police said. A fourth worker was treated for injuries on-site and released.

An Alexandria firefighters labor organization described what happened as a “serious medical event” and the victims as “severely injured after coming in contact with a power line.”

Stevenson Avenue was temporarily closed and power to the site was shut off as authorities investigated. The street has since reopened and power has been restored, police said.
