Merrimac police released a sketch Monday of the suspect in a Saturday night home invasion which woke a woman from her sleep.

The man, who had a knife, allegedly entered the woman's home on Hillside Avenue around 11:10 p.m. He threatened the woman with the knife and assaulted her, Essex County District Attorney spokeswoman Carrie Kimball said in a statement.

The victim worked with sketch artist Ian Spencer of the Lincoln, Mass. police department to create an image of the man. The suspect is described as a white male 5’5 to 5’6” tall, approximately 40 years old with short brown hair, a thin build and a light complexion with a seasonal tan.

After the attack the woman was able to escape from her house and call police from a neighbors home, according to Kimball, who said the man was gone from the house when police arrived. He is still at large, according to Merrimac police.

Police asked anyone with information to call 978-346-8321.
