The mother of missing university student Libby Squire has been photographed hugging a police officer as the search enters its 10th day.
Lisa Squire and her husband Russ today attended a vigil for their missing daughter at Hull Community Church.
Police officers are continuing to search a property on Raglan Street in Hull, where a 24-year-old man was arrested on Wednesday night.
Humberside Police were last night granted an extra 24 hours to question butcher Pawel Relowicz over her disappearance.
A large police van could be seen at the bottom of Raglan Street, less than half a mile from where Libby lived on Wellesley Avenue, with several officers walking in and out of the property.
Officers have until 9pm tonight to charge or release the man.
Libby, 21, who is originally from High Wycombe, Buckinghamshire, was last seen on Thursday January 31 when she got a taxi home from a nightclub.
Officers have said she was dropped off near her home at 11.29pm and was seen around 10 minutes later near a bench on Beverley Road, where a motorist stopped to offer help.
An intense search has been mounted by police and volunteers since then, with today marking the 10th day since she disappeared.
The vigil is believed to have involved prayers, music and the lighting of candles.
Meanwhile officers used high-tech infra-red cameras to search outbuildings near the philosophy student’s home.
The cameras are capable of detecting people who are obscured by cover and are equipped with a microphone to hear hidden movements.
Police are believed to be examining CCTV footage which shows a man getting in and out of a car minutes after the last sighting of the student.
The footage, obtained by ITV News, appears to show a man sitting with his legs out the driver’s side door of a parked vehicle in Hull, close to where the philosophy student is thought to have disappeared.
He leaves the car and, a minute and a half later, a man then is seen opening the front passenger side door and moving around before getting behind the wheel and driving away at around 12.09am on February 1.
Neighbours have also been quizzed by detectives who handed them a form with seven questions to complete.
A source told the Sun: ‘It asked where they were the night Libby went missing, if they know her, had they seen any suspicious activity in the street before the arrest and had they ever noticed the car before.’
Police used sticks and cameras to scour gardens and alleyways in the area around Libby’s home this week.
On Saturday, the force also unveiled digital missing posters, featuring pictures of Libby and an appeal for information, in the city centre.
Detectives said they were still treating her disappearance as a missing persons investigation.
Detective Superintendent Matthew Hutchinson said: ‘I have said previously that we are keeping an open mind as to her whereabouts and that is still very much the case.
‘Our number one priority is to find Libby Squire and we are still conducting extensive searches and appealing for any information from the public.’
Earlier this week, Libby’s parents issued a statement thanking people for their support in trying to find their daughter.
A JustGiving page set up to help them has since raised more than £3,000.
Craig Hopkins, who set up the page, wrote: ‘Libby’s parents obviously have a tremendous amount to deal with at this time and the last additional problem they need is any financial concerns, especially as their daughter is a student in Hull, which is a considerable distance from the family home in Buckinghamshire.
‘Even if you can only spare a few pounds, please do so, as all money raised will be sent to Libby’s parents to assist them financially at this emotionally challenging time.’
Students at the University of Hull have been told that the student wellbeing team is available for anyone who needs support.
