A supporter has been arrested after confronting Arsenal manager Arsene Wenger during the Gunners’ 2-0 defeat at Southampton.
The fan ran with his arms outstretched in front of the Frenchman as he sat in the dugout late on in the Premier League game at St Mary's.
Footage showed the man being bundled away down the tunnel by two stewards as Wenger held his arm out in apparent frustration at the intruder.
The incident capped a miserable New Year’s Day for Arsenal, whose goalkeeper Wojciech Szczesny gifted the Saints victory with two howlers.
It was unclear whether the fan who ran in front of the Arsenal manager was an Arsenal or Southampton supporter.
Police said a 25-year-old man was arrested on suspicion of "going into an area adjacent to the playing area contrary to the Football (Offences) Act 1991".
The suspect, from Lymington, Hampshire, was still being questioned on Thursday night by Hampshire Constabulary officers.
A Hampshire Police spokesman said: "Police have arrested a 25-year-old man from Lymington following an incident on the pitch at St Mary's at the end of the Southampton versus Arsenal match.
"The man was arrested on suspicion of going in to an area adjacent to the playing area contrary to the Football (Offences) Act 1991.
"The man remains in police custody. Officers are investigating the circumstances to establish whether any criminal offences have been committed."
