By David StringerLONDON -- Britain's biggest-selling newspaper was fighting to contain the damage after five employees at The Sun tabloid were arrested Saturday in an inquiry into the alleged payment of bribes to police and other officials. Rupert Murdoch's News Corp. ( NWS), which owns the newspaper, said police had searched their homes and the group's London offices, potentially deepening the scandal over British tabloid wrongdoing. The Sun's deputy editor Geoff Webster, picture editor John Edwards, chief reporter John Kay, chief foreign correspondent Nick Parker and reporter John Sturgis were those arrested, News International CEO Tom Mockridge said in a message emailed to staff. Executives moved quickly to reject claims that Murdoch could decide to close down the newspaper. In July, he shuttered the 168-year-old News of The World tabloid amid public outrage when the extent of its phone hacking of celebrities, public figures and crime victims was exposed. > > Bull or Bear?

Mockridge acknowledged that the tabloid and its employees were "facing our greatest challenge," but urged them not to prejudge the outcome of the police investigation. A 39-year-old female employee at Britain's defense ministry, a 36-year-old male member of the armed forces and a 39-year-old serving police officer with Surrey Police, were also arrested Saturday, police said. The development follows the arrest of four current and former journalists at The Sun newspaper last month in connection with the same bribery inquiry. Sun editor Dominic Mohan expressed his alarm at the arrests of newspaper employees, but insisted the six-day-a-week newspaper would continue its work. "I'm as shocked as anyone by today's arrests, but am determined to lead The Sun through these difficult times," Mohan said in a statement. "I have a brilliant staff and we have a duty to serve our readers and will continue to do that. Our focus is on putting out Monday's newspaper." Two people familiar with the matter, both of whom requested anonymity because they were not authorized to publicly discuss the issue, said Murdoch was scheduled to head to London in the near future to spend time with the company's journalists. One person explained that the trip had been planned for some time and wasn't in reaction to the latest arrests.
