Pakistan Test opener Yasir Hameed has reportedly claimed his team-mates were involved in fixing "almost every match".
The News of the World also said the International Cricket Council (ICC) is investigating a fourth Pakistan player, who has not yet been named, over match-rigging claims.
Test captain Salman Butt and bowlers Mohammad Asif and Mohammad Amir are now the subject of police and ICC investigations after the newspaper published details of the spot-fixing claims last weekend. They have now followed up with an interview with Hameed, who played in the fourth Test at The Oval.
He does not name any team-mates but is quoted in the newspaper as saying: "They've been caught. Only the ones that get caught are branded crooks. They were doing it in almost every match. God knows what they were up to. Scotland Yard was after them for ages. It makes me angry because I'm playing my best and they are trying to lose."
The new allegations follow an apology on behalf of the three players from Pakistan Twenty20 captain Shahid Afridi, who said: "On behalf of these boys - I know they're not in this series - I want to say sorry to all cricket lovers and all the cricketing nations."
The International Cricket Council (ICC) has charged the trio of players under their anti-corruption code and provisionally banned them from playing in any match. They were released without charge yesterday after being questioned under caution by detectives at Kilburn police station in north-west London.
