The Bishop of Southwark has been mugged near his home in south London.
The bishop suffered a badly bruised head from the attack
The Right Reverend Tom Butler had his mobile phone, briefcase and spectacles taken in Tuesday night's attack near his house in Streatham.
A spokesman said: "He does not remember very much at all. He got a bump on the back of his head.
"He is OK and is in good spirits. He is back at work and really wants to downplay it." The bishop, 66, was walking home from a church event.
The bishop was so bruised in the attack he was not able to wear his mitre the following day.
He began a ceremony for a new priests' institution at All Saints Church in south London by apologising to the 300-strong congregation for not wearing it.
