Three masked men knocked on the front door of a house then brutally stabbed and attacked the terrified family inside.
It is believed that three men, wearing dark clothing and balaclavas, forced their way into the property in Wood Street, St Helens, at about 11.30pm last night.
A 53-year-old man in the house answered a knock at the front door when the three men forced their way in and attacked him and a 43-year-old man in the property, who was stabbed in the stomach, back and chest.
A 19-year-old man at the address who had been upstairs heard the commotion and ran down. While trying to intervene he suffered a cut to his shin.
