An elderly victim of the Night Stalker said "oh hello, we meet again", believing him to be the same man that burgled him a month earlier, a court heard.

The man, who is still alive, heard a noise in his garden at 2am on August 17, 2009 and went to investigate.

After he checked the window and door locks he went to return to bed, turned on the stairs and saw a black clothed balaclava clad man standing on the stairs.

He said: "I spoke to my son and I realised it was wrong of me to start investigating myself.

"If I had phoned the police straight away the intruder may have been caught.

"I wasted so much time checking the windows."

It is then alleged the defendent, Delroy Grant, motioned the man to go into his bedroom, helped him undress, then sexually assualted him.

The man said: "I thought he was going to murder me.

"I was praying for a quick death.

"But no, he started putting his hands around me, on my back, on my shoulders.

"Only then I realised it was probably sexual."

The man then described how his attacker sexual assaulted him before leading him downstairs, partially clothed, to his study.

He said: "I think he said put your clothes on.

"We went downstairs to my study, which is in the living room.

"He motioned me to sit at my desk."

It is then alleged Mr Grant demanded money off the man and when he only received £15 demanded more.

The man took out his purse and gave him another £40 but his attacker also took his bank card.

The prosecution then say Mr Grant tried to use the card at a cash point, a petrol station and an off-license close to the home he shared with his disabled wife in Honour Oak.

The trial continues.
