Police have released CCTV footage of a man they want to identify in relation to an investigation into the attempted rape of a 17-year-old girl.
The teenager was walking her dog in Crawley on Tuesday evening when she was grabbed by a man.
She was able to break free and call for help, causing the man to flee.
The girl is now being supported by specialist officers. Sussex Police have increased patrols in the area and are carrying out area searches as part of an ongoing investigation into the incident.
The 17-year-old was walking along the pathway from Overdene Drive towards the tunnel that runs underneath the A23 and follows on to Quantock Close when she was attacked, between 7pm and 7.15pm on Tuesday.
She turned around before the end of the tunnel and walked back along the path to Overdene Drive.
As she did so, she crossed paths with a man who grabbed her and attempted to rape her.
The teenager was able to break free and call out, with the man then making off in the direction of the tunnel.
The man has been described as white, in his late teens to late 30s and between 5ft 9in and 5ft 10in tall.
He has dark eyes, short, dark-coloured hair and short dark stubble.
He spoke with an eastern European accent and was wearing dark clothing.
Investigating officer Detective Inspector Allana Hughes said: "We are appealing for anyone who witnessed the sexual assault or any suspicious behaviour at this location around the time of the incident to make contact with us.
"We would particularly like to hear from people who were in Quantock Close, The Dingle or surrounding roads around this time, or anyone who may have dashcam, ring doorbell or CCTV footage which might have captured the man fleeing the scene.
"We have increased our patrols in the area and have been conducting areas searches alongside investigating any potential lines of enquiry.
"Please come forward to us with any information which you think could help our investigation, no matter how small."
Sussex Police have also released CCTV footage of a man who they want to identify in connection with their investigation into the incident.
Information can be passed on to the force online or by calling 101 quoting Operation Stockbridge.
Alternatively, people can report information anonymously via the independent charity Crimestoppers either online or on 0800 555 111.
