THE BRONX - A civil liberties group is questioning police tactics when it comes to searching the property of teens.

The group, 100 Blacks in Law Enforcement Who Care, says that when police stop teens carrying T-Mobile-manufactured Sidekicks, they check the serial numbers to see if they?re stolen. It?s a practice that the group says unfairly targets teenagers and violates their constitutional rights. Members of the group say it also creates friction between police and teens.

Sidekicks have become popular among teens who say they enjoy its different features, but police say that they?ve also become a target for thieves.

The NYPD says that its officers never look at phones without permission from the owner. 100 Blacks in Law Enforcement says it will continue monitoring complaints from teenagers in the Bronx and citywide.
