Holly Albert, 30, has been charged with second-degree assault after throwing a house phone at her mother's head in Potomac, Maryland

A 30-year-old woman has been arrested for throwing a phone at her mother's head because she wouldn't drive her to a yoga class.

Holly Albert, who is unemployed, has been charged with second-degree assault over the bloody incident at her family home in Potomac, Maryland.

Albert, who was only arrested last month despite the incident occurring 18 months ago, left her mother bleeding profusely from the head following the ordeal.

Her mother had called 911 to report the domestic violence incident.

Police arrived to find the mother wearing a blood-soaked shirt with her hair matted down, according to court documents obtained by ABC7.

She told officers that Albert had wanted to go to a yoga class but she became furious when she refused to drive her daughter there.

Albert allegedly started shouting insults before grabbing the house phone and throwing it at her mother's head.

Her mother suffered a huge cut on her head that caused a 'large amount of bleeding'.

She used that same phone to call 911 while her daughter left the house.

A warrant for Albert's arrest was issued that day but she was only arrested in February.

It is not clear why she wasn't taken into custody sooner.

Even though she initially called 911 to report the incident, Albert's mother filed a statement with the court urging a judge to allow the 30-year-old to continue living in the family home.

'I freely state that at all times since those events, up to the present, Holly Anne has lived with me and her father without any incident or reason whatsoever that would cause either of us to fear for our safety or well-being,' Albert's mother wrote.

'Moreover, I believe that it is in Holly Anne's best interest that she continue to reside with us, rather than have to make other living arrangements pending a future trial date.

'Holly Anne is currently unemployed and we are providing her with financial and other support at this time. It is Holly Anne's wish and decision to address and resolve the subject proceeding, and to that end she is voluntarily surrendering herself to the outstanding warrant.

'Knowing Holly Anne as I do, I am confident that she intends to appear at every court date necessary to bring this matter to a close.'

Albert was released on an unsecured bond and is due to face Montgomery County District Court on March 19.
