FORT LAUDERDALE, Fla. -

An undercover sting involving men soliciting sex from underage boys on the Internet has now led to the arrest of seven suspects.

Broward Sheriff's Office detectives said they used a cellphone app named "Jackd" to pose as a 15-year-old boy in each instance.

Detectives said the men arranged to meet the teen, but they were arrested upon arriving at the meeting location.

The men were charged with traveling to meet a minor and soliciting a child using the Internet.
