A 37-year-old Waltham man was arrested Wednesday for allegedly stabbing two women, including one victim who is in her 80s, inside a city home earlier in the day, officials said.

The attack occurred shortly before 1 p.m. inside a house on Weston Street, according to Middlesex District Attorney Marian T. Ryan's office.

An 83-year-old woman suffered a cut on her hand, and the second victim, age 52, suffered multiple stab wounds and was listed in critical condition on Wednesday afternoon, Ryan’s office said in a statement.

Both women were taken to area hospitals.

The suspect, Emanual Louis, 37, fled from the scene but was later apprehended by Waltham police, authorities said. Officials did not indicate when or where he was arrested.

“The victims and the suspect in this incident are known to each other and this attack is not random,’’ said the statement from Ryan’s office.

The two women and Louis “are not related to each other or Louis,’’ Meghan Kelly, a Ryan spokeswoman said in an e-mail.

“The investigation into this matter is still ongoing,’’ Kelly said.

Prosecutors did not disclose a possible motive for the attack.

Louis faces charges of armed assault with intent to murder, assault and battery with a dangerous weapon causing serious bodily injury, and assault and battery with a dangerous weapon on a victim over 60.

He is scheduled to be arraigned Thursday in Waltham District Court.

A Waltham police dispatcher said no one was available to comment.
