A young woman has spoken of her terror after she was followed by a man wearing a burqa and hit over the head with a brick in a savage attack.
The 23-year-old was chased by Hong Nguyen in Streatham Park before he smashed her over the head from behind.
On Friday he pleaded guilty to attempting to cause grievous bodily harm – but his victim has been left with traumatic nightmares and flashbacks of the attack.
