Mirror Sport understands the ex Arsenal defender, 35,Emmanuel Eboue has been taken to police station in north London.
Police said a man has been detained on suspicion of arson and malicious communications outside a home in Enfield.
Friends are understood to be concerned for the former full-back’s mental and emotional state.
They also fear he is unable to afford legal representation after being left broke following a failed appeal against his acrimonious divorce.
“He has been bailed for further enquiries in relation to the other offences.”
Eboue appeared to have been thrown a lifeline last month when he was invited to play for the Gunners’ legends side at the Bernabeu in Spain.
He appeared alongside greats such as Nicolas Anelka, David Seaman, Sol Campbell and Ray Parlour for the star-studded charity match.
But his situation remains fragile sparking the concerns for his welfare.
The Ivory Coast international told the Sunday Mirror last Christmas of his plight since his playing days – admitting he had been left homeless following a divorce.
