British police make fourth arrest in TalkTalk cyber attack

British police have made a fourth arrest in connection with a cyber attack on telecoms company TalkTalk (TALK.L) in which the company said bank details of more than 20,000 customers were hacked. A 16-year-old boy from Norwich in eastern England was in custody and his address was being searched, London police said in a statement on Tuesday. TalkTalk shocked customers last month when the broadband, TV, mobile and fixed-line service provider said it had been hacked, potentially putting the private details of its 4 million customers into the hands of criminals.
