WASHINGTON, Nov 13 — A disgruntled tenant shot dead his building manager and wounded four other people in an upscale neighbourhood of Washington yesterday before killing himself, police said amid a massive law enforcement response that shut down part of the city.

The shooting, which occurred about a mile north of the White House, sparked a massive police response in the nation’s capital with dozens of law enforcement vehicles racing to the scene and police helicopters hovering overhead.

Dramatic dispatch audio captured the initial callout for a shooting inside the gym just before 8am (0100 GMT). Within minutes a breathless police officer could be heard telling the dispatcher “we have an active shooter” and requesting the SWAT team.
