West Ham forward Diafra Sakho has been arrested on suspicion of common assault.
Police officers made their move last Thursday, just three days before the Hammers recorded a shock 2-0 win over Arsenal at the Emirates Stadium, following allegations the 25-year-old attacked a woman.
Sakho was arrested at his Essex home, in Hornchurch, before being taken to an east London police station.
The striker, who cost West Ham £3.5m last year, was also arrested on suspicion of criminal damage and malicious communication.
The Senegal international has been bailed and is due to return at a date towards the end of next month.
A police spokesman confirmed: “Officers from Tower Hamlets have arrested a man on suspicion of common assault, criminal damage and malicious communication.
“The 25-year-old was arrested on Thursday, 6 August at an address in Emerson Park, Hornchurch.
“He was taken to an east London police station and has been bailed to a date in late September.”
West Ham declined to comment on the matter on Tuesday.
The incident didn’t prevent Sakho from featuring heavily in Slaven Bilic’s plans against the Gunners on Sunday, the Croatian’s first league game in charge of the club.
He started the London derby, playing in virtually all of the encounter, replaced in injury time by Modibo Maiga as the Hammers ran out 2-0 winners.
Sakho moved to West Ham last summer in a £3.5m deal from FC Metz in France.
Last season he played 23 Premier League games, scoring 10 goals and providing two assists.
Earlier this month magazine pictures of him with girlfriend Mya emerged in an online forum claiming she was pregnant.
