Motorists and pedestrians asked about Mary Coulter attack
Police investigating a brutal attack on a grandmother at her North Lanarkshire home have stopped and questioned local motorists a week after the attack.
Four men attacked 76-year-old Mary Coulter at her home in Overtown, near Wishaw, at about 05:20 on 22 March.
Her son and grandson had been among three men cleared of killing Asian waiter Surjit Singh Chhokar in 1998.
Officers questioned drivers and pedestrians in the Overtown area between 04:45 and 05:45 on Thursday.
Mrs Coulter suffered serious head injuries during the attack, cuts to her face - which have left her permanently scarred - and two broken arms.
Police are treating the incident as attempted murder.
Mrs Coulter is still being treated in hospital where her condition is described as stable.
The four men smashed down the front door of her ground floor flat and assaulted her in the hallway with a knife and a bat.
After she ran into the street, they chased her and continued the attack.
The men ran off after Mrs Coulter's neighbours were alerted to her screams.
Police hope that by questioning drivers and pedestrians in the area they will help jog their memories and trace potential witnesses who may have been in the area at the time of the attack.
The Crimestoppers Charity is offering a £5,000 reward for information which leads to the arrest and prosecution of Mrs Coulter's attackers.
The suspects were all white men. They were either wearing hooded tops or had scarves over their faces. One is described as being particularly heavily built.
Police believe Mrs Coulter was not the intended victim of the attack.
Mr Chhokar's murder in 1998 sparked controversy after the failure of authorities to secure a conviction.
Three men, including Ronnie Coulter and his nephew Andrew Coulter, were cleared of the killing following separate trials.
Last month the Crown Office instructed Strathclyde Police to carry out a new investigation into Mr Chhokar's murder under double jeopardy legislation introduced last year.
