Police searching for a missing 16-year-old girl have asked people who were marking VE Day earlier this month to check their videos to see if they captured her walking by.
Louise Smith, from Havant, was last seen in Somborne Drive in the Hampshire town at around midday on Friday 8 May.
The date was a bank holiday and coincided with when people across the country were commemorating the 75th anniversary of the end of World War Two in Europe.
A man and woman, both 29, were arrested on suspicion of kidnap but have since been released on bail.
Detectives were able to trace Louise’s phone to a skate park in Havant but it has since been turned off, Portsmouth News reported.
Hampshire Police said she has not been in contact with her family since she went missing.
The force added that the girl’s disappearance is being treated as a missing person investigation.
Chief Inspector Alex Reading said: “We know a lot of people would have been out on their driveways on VE Day, and may have been filming the celebrations in their neighbourhood on camera or mobile phone.
“If you were out celebrating or filming on VE Day in Leigh Park, we ask you to please take a look back over your footage to see if you captured Louise walking by.
“Perhaps you drove through the area on VE Day and saw someone matching Louise’s description, or caught her on dashcam. Please check your dashcam footage from this day to see if it captured anything that could help our investigation.”
Officers have also asked anyone who may have witnessed something significant to come forward.
The force said Louise’s disappearance is “very out of character for her and both her family and police are understandably concerned for her welfare”.
Officers along with Hampshire Search and Rescue have been carrying out “extensive” searches in the Havant Thicket and Staunton Country Park areas.
Hampshire Police have also asked the teenager to get in touch with them if possible.
Louise has been described as white, around 5ft 2ins tall, of slim build, and with straight, black, shoulder-length hair.
Police have said they cannot be sure what she was wearing at the time of her disappearance.
They added she was described as wearing black jeans, a black and white striped t-shirt, black trainers and a black coat with a fur hood on 7 May.
