Police have issued CCTV images of a suspect wanted in connection with an armed robbery at the Gleneagles Hotel.
A 41-year-old man was earlier charged in connection with the incident, which took place on 27 June.
At least 50 designer watches worth £500,000 were stolen by masked raiders at a jewellery boutique inside the hotel.
Officers said staff at the store were threatened with a firearm during the robbery but no shots were fired.
The 41-year-old is expected to appear from custody at Perth Sheriff Court on Monday.
Police Scotland said the suspect, who is pictured at a railway station and a branch of WH Smith, is believed to have links to the London area.
