Engineers are trying to find out what has caused a giant hole that opened up in a Melton Mowbray car park.
The 10ft wide gap appeared outside the town's railway station last week and the area remains cordoned off, while investigations continue.
Station staff are intrigued by what is below and ask for people who know about the area's history to come forward and see if they can provide answers.
Julie Wilkinson from the station said the hole has been growing.
