The World: Chicago - DDB Chicago's Paul Tilley dies in apparent suicide

Paul Tilley, DDB Chicago's award-winning creative chief, has died in an apparent suicide. Tilley, 40, is thought to have died after falling from Chicago's Fairmont Hotel, which is next door to the agency.

Chicago police said the incident remained a "death under investigation".

Tilley, who had been at the agency for 11 years, took over as the managing director for creative in September 2006. At the time, he called it a "dream job" and set about trying to restore flagging growth at the agency, whose clients include McDonald's and Anheuser-Busch.

Rick Carpenter, the DDB Chicago chief executive, described Tilley as "a mentor to many and a friend to all". He added: "The reality of this news is difficult to comprehend."
