LONDON — Amy Winehouse’s husband beat up a pub landlord and then offered him $400,000 to keep quiet about the attack, a prosecutor said Tuesday.

Prosecution lawyer Sean Larkin said barman James King suffered a broken cheekbone in the June 2006 attack by Blake Fielder-Civil and another man — but was willing to accept money to spare his attackers jail.

King, 36, is on trial for conspiring to pervert the course of justice (the equivalent of obstruction of justice in the U.S.). He denies the charge, and says he was intimidated into withdrawing the assault claim.

Larkin told the jury at Snaresbrook Crown Court that a deal had been struck for King to retract his statement, leave the country and not show up for any trial, “and that Mr. King expected to be paid something in the order of 200,000 pounds.”
