Teen jumped from window on second floor 'to flee burglar' threatening to 'blow up house'
Michael Cummins (30) also locked the front door, and when gardai entered the house, a second "frightened" teen was found in the hallway, Dublin District Court was told.
Mr Cummins, a father-of-two, is charged with burglary in Main Street, Applewood, Swords.
Gardai objected to bail, citing the seriousness of the charge and the strength of the evidence. Mr Cummins was remanded in custody for one week and has not yet entered a plea as to the charge.
Garda Miriam O'Donovan told the court that Mr Cummins allegedly approached two teenagers, one aged 13 and another aged 15, in Main Street.
Gda O'Donovan claimed the accused was highly agitated and aggressive and pocketed a mobile phone belonging to one of the teenagers.
She alleged Mr Cummins then walked into a nearby house and picked up a wallet in the kitchen.
He went upstairs where he filled a shoulder bag and a laptop bag with a number of items, including an iPod.
Gda O'Donovan alleged that Mr Cummins locked one of the teenagers in a bedroom and threw the key down stairs.
He was aggressive and threatening, and told the teenagers that he would "blow up the house", the court heard.
Gda O'Donovan said the teenager jumped from the bedroom window in his bare feet to get out of the house.
The court heard that gardai were called, and when they arrived the front door was locked from the inside and Mr Cummins was at the scene.
Mr Cummins was allegedly unco-operative and negotiations began for him to open the door.
Gda O'Donovan said that when gardai entered the property, the second teenager was in the hallway.
Defence lawyer Aoife O'Halloran said Mr Cummins was willing to abide by any bail conditions, including a curfew and sign on conditions.
Ms O'Halloran also said the accused was welcome to reside at his mother's home in Applewood Avenue, Swords.
Judge Alan Mitchell refused bail and remanded Mr Cummins in custody.
As he was led from the courtroom by prison officers, Mr Cummins told the judge he was "a f**kin' joke".
He also called Gda O'Donovan a "lying, fat b***h", described the court as "a circus" and said he'd "rather be in Africa".
Judge Alan Mitchell ordered medical attention for the accused whilst in custody.
