London: England completed a crushing innings and 225 run victory over Pakistan in the fourth and final test at Lord's on Sunday on a morning overshadowed by corruption allegations.
Police arrested a 35-year-old man on Saturday after a British newspaper said Pakistan players had been involved in spot fixing, the illegal practice of manipulating incidents within the course of the match.
In an innings in keeping with an unusual game, Umar Akmal smashed 79 not out from 68 balls including two sixes in a total of 147.
He shared a last-wicket partnership of 50 with Mohammad Asif, who contributed only one, but still could not prevent Pakistan tumbling to the biggest defeat in their test history.

England won the series 3-1 after dominating the first two tests before they were defeated by four wickets in the third match at the Oval. Pakistan, who played six tests in seven weeks, drew 1-1 with Australia earlier in the season.
Pakistan resumed at 41 for four in their second innings before a scattering of spectators on a dull, overcast day.
They left their north London hotel late on Sunday morning and did not take part in the usual team warm-up before play began.
Off-spinner Graeme Swann, who took four for 12 in Pakistan's first innings of 74, was again the destroyer with five for 62.
Swann bowled Azhar Ali for 12 and Mohammad Amir for a duck as three wickets fell in the space of 11 balls.
Wahab Riaz was caught by Kevin Pietersen at mid-on off Swann without scoring before Umar Akmal flourished with a frenetic innings including a huge six over long-on in his first half-century of the series.
