Two Harford County teenagers were arrested in separate incidents for allegedly threatening someone in their household with a knife earlier this week.

In a third incident, a Bel Air man was also accused of cutting his brother with a knife on Christmas Eve.

Zachary T. Mulgrew, 17, of the 700 block of Shallow Ridge Court in Abingdon, was accused of threatening his 19-year-old fiancee with a knife on Monday, according to a police statement of charges.

Mulgrew was making food and holding a six-inch kitchen knife, according to the charging document. During an argument, Mulgrew allegedly approached the victim and began to wave the knife close to her face, saying "I wish I could do it to you and not stop."

The victim also said that earlier in the day Mulgrew allegedly grabbed her throat and pushed her head into the wall, according to the statement of charges.

Mulgrew told police he was just joking around, but the victim said she believed he was actually going to cut her with the knife, according to the statement of charges.

Mulgrew was charged as an adult because of the first-degree assault charge, according to the statement of charges.

He was released on his own recognizance, according to online court records.

Edgewood incident

On Tuesday, Howard L. Adams, 19, of the 300 block of Redbud Road in Edgewood, was arrested at his home after he allegedly threatened his roommate with a knife, according to a statement of charges.

The victim told police they were playing video games when Adams began to make fun of the victim's mother, according to the statement.

The victim's girlfriend said that, after an argument, Adams allegedly went upstairs, retrieved a butcher's knife and pointed it at the victim from the top of the stairs, according to the statement.

The detective was unable to find the knife in question, but arrested Adams. He was charged with first-degree assault and second-degree assault, according to online court records.

He was also released on his own recognizance the same day.
