Issue with Bootstrap carousel on Chrome (non-iOS)

I’m working on my portfolio project, and have used the default bootstrap carousel to showcase some images of projects.

I followed the approach used on w3schools: http://www.w3schools.com/bootstrap/bootstrap_ref_js_carousel.asp

Just sent it to a friend to test, and on a mobile the carousel slide action causes the page to scroll to the head (or #)

I can’t see anything obvious - can anyone else help?
