SARASOTA, Fla.—Lego man is going to stay in police custody for three months.

Lego man, a 100-pound, 8-foot-tall sculpture, didn't do anything wrong except wash up on a Florida beach. Sarasota County Sheriff Tom Knight says his office will hold the fiberglass sculpture for 90 days just like all other lost and found property.

During that time, authorities will try to determine who the owner is.

The Sarasota Herald-Tribune (http://bit.ly/uExBYk) reported that the local tourism bureau had hoped to use the Lego man to promote the area, but the sheriff says it needs to remain in police custody a little longer.

The sculpture mysteriously appeared on a Siesta Key beach Tuesday.

A Legoland recently opened in Winter Haven, which is about 70 miles northwest of Siesta Key.
