Chelsea are reportedly mystified after £30,000 worth of high-tech camera equipment used in training disappeared from their Cobham headquarters.
According to The Sun, the club called Surrey Police over the missing gear.
While it is not currently known whether the equipment had simply been mislaid, the incident has been deemed suspicious enough for the police to become involved.
Just like many other elite clubs, Chelsea use video footage from training sessions and matches extensively to aid their players' tactical understanding.
It has also proven beneficial for physical preparation before games.
Chelsea declined to comment on the timing and circumstances of the discovery, but more details could come to light once all staff members return from holiday.
