Lost & found passports in Kent

Passport found near Canterbury West station, blue cover

I found a passport this afternoon around 3:15pm behind Canterbury West railway station, off Station Road in Canterbury, Kent. The cover is a dark blue with a lightly embossed crest and a small coffee stain along the back edge; the spine is a bit worn from handling. Inside, the data page shows the name 'M. Patel' and there is a faint visa stamp from a country I can't quite read, plus a tiny sticker with the word 'Lena' tucked under the photo. I know how stressful it is to lose a passport, so I’m hoping to help reunite it with its owner.
