AKRON, Ohio (AP) -- An Ohio man has been sentenced to more than 11 years in prison for sex-trafficking involving a 16-year-old at a Starbucks coffee shop in Cleveland.

Federal Judge John Adams in Akron sentenced 44-year-old Eric Tutstone of Cleveland on Tuesday for offering to sell the girl into the commercial sex trade for $300 in December 2011.

He was convicted on two counts of sex trafficking.

The purported buyer was an undercover informant who was once a madam in the sex business.

The Starbucks manager in Cleveland's upscale Warehouse district said at the time that the shop was unaware of what was going on.
