All Clear After Clark/Lake Station Evacuated, Loop CTA Trains Halted Due To Unfounded Threat

CHICAGO (CBS) -- A threat prompted authorities to evacuate the busy Clark/Lake CTA 'L' station late Wednesday afternoon.

Loop trains were halted for about half an hour before an all-clear was given around 4:45 p.m.

Police said they were investigating the viability of a threat to the Clark/Lake station. Commuters were advised that there would be a heavier-than-normal police presence.

The threat proved to be unfounded, police said.

The Clark/Lake station is composed of an elevated platform alongside the Thompson Center that serves the Pink, Green, Brown, Orange, and Purple line stations, and a Blue Line subway platform.

The CTA said trains on all those lines were left standing near Clark/Lake after the threat was received.

Blue Line service was shut down, and O'Hare-bound Blue Line riders were told to evacuate at Washington. No reason was provided to the riders.

Some CTA passengers expressed confusion on Twitter – reporting that there were no trains going into or out of the station and that they were not told why the station was evacuated.

@cta what's happening at Clark/Lake? Everyone was removed from the train and not allowed to board.
