A teenager says she was left incoherent and unable to walk after being spiked - at a Taylor Swift concert.

Grace McAleavy, 18, started getting confused and slurred her words while she watched the megastar perform at Liverpool's Anfield Stadium on Friday (June 14).

She says she felt fine before the show started and hadn't drank any alcohol - but when Taylor started her '1989' set, she thought she was going to be sick.

The teenager then started slurring her words and eventually was unable to walk - and now she believes she was spiked at the sold-out gig.
