SAN JUAN, Puerto Rico (AP) — Authorities in Puerto Rico are searching for a U.S. tourist they say got lost in the dense tropical rain forest of El Yunque in the U.S. territory's east.

Police said in a statement that Abdur Rahman, 64, was hiking with a group when he became separated from them on Sunday.

Crews resumed their search on Monday for Rahman, who police said lives in Wisconsin.

El Yunque is a popular tourist spot and the only tropical rain forest overseen by the U.S. Forest Service.

Last year, a U.S. tourist died after authorities said he fell off a cliff after leaving a designated hiking area.
