Stalked by a van near the science park

Had a very weird experience yesterday evening around 8:30pm. Basically I was cycling along Grenoble road between the A4074 and the science park when I became aware that a white Vauxhall Astra Estate van was following me (didn't catch the reg but model year 2004-2010). It then pulled alongside me and the passenger started staring at me through the open window, didn't say anything but was looking me up and down. So I quickly cycled into the science park (I figured there'd be cctv around there) and it sped up and followed me. Luckily I managed to dart into a car park and hid there for a bit, but I saw the van return 5 mins later so it was clearly looking for me.

Anyone else had anything like this happen? Stay safe out there.
