Naresh Kumar, 50, saw the girl in Addison Howard Park in Kempston on 26 August when he intercepted her and took her into a nearby obscured area and sexually assaulted her.
A couple walking their dog saw something was happening and shone a torch towards them which caused Kumar to let go of the girl and she was able to run to them for help.
He will also be subject to a deportation order after his sentence is served.
