A 28-year-old man has been arrested on suspicion of selling former Downing Street chief of staff and Cork man Morgan McSweeney’s stolen phone.
Scotland Yard took the man into police custody last Wednesday and he was later bailed.
He is not suspected of involvement in the original theft on October 20th last year, the force said.
Concerns have been raised that the theft could result in important messages about Peter Mandelson’s appointment as US ambassador being lost.
A Metropolitan Police spokesperson said: “Officers investigating the theft of a mobile phone in Belgrave Road, Pimlico, on October 20 2025 have arrested a 28-year-old man on suspicion of handling stolen goods.
“The arrest took place on Wednesday April 29 at an address in Peckham. The man was taken into police custody and later bailed.
“He is suspected of receiving the phone after it was stolen and then selling it on. He is not suspected of any involvement in the original theft.
“The phone has not been recovered.”
