'Black Friday': Police called to supermarket crowds

Greater Manchester Police appealed for calm after attending seven Tesco shops, at which three men were arrested and a woman was hit by a falling television, BBC News reports. The force said the issues were "totally predictable" and it was "disappointed" by shop security. Tesco said only a "small number" of stores were affected. Police were called in places including Dundee, Glasgow, Cardiff and London. Originating in the US, Black Friday is becoming a major UK shopping day. Police in Manchester tweeted: "At least two people arrested at #BlackFriday sales events already this morning. Keep calm people!" In London, police were called by both Tesco staff and queuing shoppers as people gathered at the Glover Drive store in Edmonton. Officers also attended Tesco stores in Willesden and Surrey Quays.
