Boxing icon Frank Bruno has reassured fans he is OK and merely "recharging the batteries" after checking into a clinic.
The fighter sparked fears for his health after he was admitted to a treatment centre amid reports his bipolar disorder had returned, but Bruno insists he voluntarily entered the private hospital to rest after suffering from exhaustion.
In a message to fans, obtained by Britain's Daily Mirror, he writes, "I'm recharging the batteries. The mobile phone needs it, so do I. Thanks 4 (sic) all your good wishes. FB."
In 2003, Bruno was sectioned under Britain's Mental Health Act and underwent psychological and psychiatric tests before being diagnosed as bipolar.
