The West Hollywood Sherriff’s Department received a call this afternoon from a “media source saying they received an anonymous call that the dress was in a restroom in the second floor of the London Hotel” where the actress was staying, Lt. Michael White said. “Hotel staff searched and found the dress in a bag hidden behind a counter in the bathroom. We believe this is the dress stolen from the hotel.”
There are no suspects, he said, although officials are reviewing surveillance video. A few smaller pearls appear to have fallen off the dress, but it seems to be intact, White added.
“We will maintain custody of the dress until a rep from the company or the victim comes to claim it,” he said. “We have lots of interesting things that happen in West Hollywood, we gave it the same attention we give any other case. It’s just another day in West Hollywood.”
The bathroom, which is being renovated, is accessible by both staff and visitors.
"This is a terribly unfortunate situation, and we are working with law enforcement on their investigation," a hotel representative previously told ABC News.
Nyong'o, 31, won the Best Supporting Actress Oscar last year and presented at this year's awards, wearing the custom dress that was designed for her by Francisco Costa.
Nyong'o's publicist declined to comment, while a rep for Calvin Klein has not yet responded to requests for comment.
