A mother has described her horror after an autistic teenager attacked her three-month-old baby son in his pram , leaving his face scratched and bloody . Janet-da-Silva , 30 , a mother-of-two , said she was getting off a bus in Denaby Main , South Yorkshire , with her son Gabriel Jones and her mother when the attack took place last Wednesday . She said three men were walking towards her when suddenly one launched himself forward , clawing at Gabriel 's face . Janet-da-Silva , 30 , a mother-of-two , was climbing off a bus when a teenager launched himself at her son Gabriel 's pram , scratching at his face ( pictured right with a scratch on his cheek and below his left eye ) It later emerged that the 17-year-old was a pupil at a nearby special needs school who was out walking with two carers . Ms da-Silva said : 'He shoved both hands in and clawed Gabriel ’ s face . He could have blinded him . ' I screamed : “ What the hell are you doing ? ” Then he stood up , looked at me and laughed . 'Gabriel was screaming out and I saw blood on his face and I started screaming . 'The other two men then grabbed the guy on either arm and stood him up against a wall . Neither of them said anything to me , I didn ’ t know who they were or where they were from . 'It happened so fast I didn ’ t have time to stop him . ' Despite Ms da-Silva asking the men to stop , they turned their backs and walked away . It later emerged that the boy was a 17-year-old pupil with autism who studied at nearby Fullerton House School , and had been on a walk with two carers . She added : 'They wouldn ’ t listen to me or stop . One of them said : “ We ’ ve got to get him away before he gets more angry and violent . '' ' I kept asking them where they were going but no-one gave me any information . ' Ms da-Silva left baby Gabriel to be comforted by grandmother Debbie Rojas Marinero and followed the men , eventually seeing them going into Fullerton House School . The institution caters from teenagers with learning difficulties . The pupil in question is said to have complex needs arising from his autism and has been at the school for some time . A spokesman for the school said that both carers have been suspended and an internal investigation is underway . The spokesman said : 'Due to the complexity of his disability he does not have the mental capacity to be charged . ' Chris McSharry , chief executive of the Hesley Group which runs Fullerton House said : 'This is an incredibly unfortunate incident and my thoughts are with the baby and his family . ' Ms da-Silva said she has been left afraid of going out with baby Gabriel following the attack , which took place last Wednesday ( pictured , the road where the attack took place ) However , Ms da-Silva said : ' I was disgusted by their attitude . I understand people need their freedom and sunshine but they knew the teenager was violent so why was he not walking within the school premises ? ' She has now been left scared to go out with Gabriel . 'It was the worst day of my life , ' she added . 'It ’ s broken me . I pray Gabriel does not remember but unfortunately we will . ' A South Yorkshire Police spokesman said they were aware of the incident and no arrests had been made . Any decision on a prosecution would rest with the Crown Prosecution Service .
