A mother was allegedly abused after a fellow rail passenger complained about her crying child.
Police are investigating an incident on a train at Blackpool North station, when the victim was confronted by a woman sitting opposite her.
Officers say the mum and toddler boarded the train to Blackburn at Blackpool North, when the child started to cry.
The alleged offender then complained about the noise before becoming aggressive and having to be held back by a friend.
British Transport Police have today released a grainy CCTV image of a woman they want to speak to following the incident, which is reported to have taken place at around 7.30am on August 1.
PC Ryan Moore said: “A mother and her toddler boarded a train at Blackpool North. During the journey to Blackburn the child became upset and began crying.
“A woman who was sitting opposite complained about the noise and told the woman to silence her child.
“When the mother objected, the woman became abusive and stood up to physically confront her.
“She was only prevented from attacking the mother by one of her friends who successfully restrained her.
“We believe the woman in the image could have vital information about what happened and would urge her or anyone who recognises her to come forward to assist us with our enquiries.”
