The trainer of a horse who died after suffering a fatal fall at Saturday's Grand National has blamed "ignorant" protesters for the death of the prized animal.
The British Horseracing Authority (BHA) has said it will investigate the deaths of three horses at the Grand National meeting "in painstaking detail", as it condemned protesters who disrupted the event.
An animal activist who disrupted the Grand National has warned of further protests ahead of some of the biggest horse racing events in the UK calendar.
