Procter & Gamble says security tightened at Cincinnati headquarters after Greenpeace protest

Procter & Gamble Co. says it has tightened security at its Cincinnati headquarters after a breach this week that allowed an eye-catching protest by Greenpeace.

Lisa Popyk (PAHP'-ik), a spokeswoman for the world's largest consumer products company, says steps already have been taken to improve security in the aftermath of Tuesday's protest. Nine environmental activists unfurled huge banners from the 12th floor of the corporate offices.

Popyk declined to give details of the security changes, and said she didn't know whether anyone had been disciplined for the breach. She said the company has determined from its initial investigation that one activist gained entry by claiming to have an appointment.

Police arrested the activists on burglary and vandalism charges. They were released Wednesday on $50,000 bond each.
