Mr McCrossan said: “I completely condemn this disturbing attack committed against a 22-year-old man last night.
“This man has been left seriously injured by those who think they can take the law into their own hands.
“Strabane has witnessed a spate of attacks on individuals and families in recent months, which is completely unacceptable.
“The message must be put out there, and it must be clear, that these attacks have no place in our society.
“I have been liaising closely with the PSNI on this crime and I’d ask anyone who has any knowledge of the criminals involved or their movements to ring 101 and give this vital information to the authorities.
“Only then can we weed this type of criminal activity out of our communities,” he added.
