(KMOV)-- Two workers are injured after suffering an electrical shock in downtown St. Louis.
It happened around 4:15 p.m. at the Robert A. Young Federal Building at the corner of Spruce and Tucker.
Authorities say the first worker was on some scaffolding and somehow received the shock.
The second worker received a shock about four hours later.
The shocks were not serious but both workers were transported to a local hospital to be checked out.
The fire department could not identify what caused the shock but shut down the power breaker for the area until the construction foreman could find the problem.
