A mobile phone thought to belong to a missing 15-year-old girl has been found in the area where she was last seen.
Officers investigating the disappearance of Kayleigh Haywood said the phone was found by a member of the public in the Ibstock area of Leicestershire.
Two men, aged 27 and 28, have been arrested in connection with the teenager's disappearance and are currently in police custody.
Meanwhile, Sence Valley Forest Park, on the outskirts of Ibstock, has been sealed off by search teams.
Detective Chief Superintendent David Sandall, of Leicestershire Police, said: "Our concern for Kayleigh is growing.
"She does not have her phone with her and has no way of contacting us, which adds to our worries about her safety.
"We have been trying to piece together her last movements and we believe she may have been in the Sence Valley Forest Park area on Saturday afternoon.
"I would urge you to get in contact with us if you were in the area between Saturday afternoon and Monday morning.
"This area is used by a lot of local people, particularly dog walkers, and it is these people I need to hear from."
Anyone with information is urged to call the dedicated incident room on 0800 096 1233 or 020 7158 0197.
