Missing People, the UK charity dedicated to reconnecting missing people and their loved ones, continues to appeal for information on their whereabouts and urges them to make contact. Its confidential helpline is open daily between 9am and 11pm to anyone calling 116 000.
The helpline is for people who are thinking about leaving home, who are currently missing, who have a missing loved one, or families and young people affected by exploitation. It is also how members of the public can pass on information about sightings.
