Police are increasingly concerned for the welfare of Marc Williams, 18, and Lewis Ashdown, 19, who have both been reported missing from Uckfield.
Marc (right image) and Lewis (left image) went to the Maresfield area on Saturday evening (29 May) where it is believed that they met up before going their separate ways.
Marc called his family about 11.30pm to say he was on his way home but never returned.
Lewis was last seen in Crowborough around 11am on Sunday (30 May), but has not returned home since.
Officers are carrying out house to house enquiries, CCTV enquiries and local area searches as they work to establish their movements.
Chief Superintendent Nick May said: "It has been nearly 36 hours since we have confirmed sightings of either of these two young men and we are increasingly concerned for their welfare.
"Our officers are working around the clock to establish the whereabouts of Marc and Lewis and we continue to appeal to the public to come forwards with any relevant information.
"If either Marc or Lewis are reading this then we would urge them to please make contact to let us or their families know that they are safe.
"Anyone who has seen Marc or Lewis or who has any information that may assist with our investigation is urged to report it to us immediately, quoting Operation Skittle."
