A DISTRAUGHT widower attempted to murder a schoolgirl by removing her seatbelt and "deliberately" crashing his car after discovering his wife had killed herself, a court has heard.

Nando's worker Lukasz Jarosz is accused of crashing his Skoda Superb car at a junction of the A36 at Wilton on January 6, just hours after he had found his wife Aneta hanging in their bathroom.

The 35-year-old is on trial at Bournemouth Crown Court for a charge of attempting to murder the youngster, who cannot be named for legal reasons, who suffered a fractured leg in the impact.

He denies the charge.

The Polish national has admitted a second charge of causing serious injury through dangerous driving.

Kerry Maylin, prosecuting, said the defendant had become "hysterical" after the "tragedy" of discovering his wife's body.

She said the couple had previously argued over a possible affair by the defendant with a colleague.

Miss Maylin said: "That tragedy was that Lukasz Jarosz's wife, Aneta Jarosz, had decided to end her own life and hung [sic] herself in the family bathroom of their home in Adelphi Court, Wilton.

"Lukasz Jarosz had found her some time in the early afternoon on that Friday, he cut her down, laid her on the bed, attempted to perform CPR."

She said that later that afternoon he was driving the schoolgirl who said that he was "upset, crying and at times screaming".

Miss Maylin said he would not allow the girl to leave the car and drove them "around in circles" for one hour and 25 minutes before the crash.

She said the defendant talked of suicide and at one stage he took hold of the girl's hands and locked the doors of the car which also had his dog Daisy in it.

Miss Maylin said Jarosz was driving on the A36 in the direction of Salisbury when he came off at the Kingsway Industrial Estate junction and drove at a railway bridge at an estimated speed of "no less than 40mph" in a zone with a 30mph speed limit.

She said: "It was at that stage Mr Jarosz undid the seat belts of himself and (the schoolgirl)."

Miss Maylin said the Skoda crashed into a van, driven by local worker Peter May, before striking the bridge and spinning to a stop causing severe damage to both vehicles.

She said witnesses saw him get out of the car and say "my wife killed, my wife killed" and "at one point made a hanging motion with his hand behind his neck".

Miss Maylin said the schoolgirl was trapped in the front passenger seat and had to be freed by firefighters.

She told the jury: "However sad and tragic it may be, the prosecution will invite you in due course to consider that when he undid the seat belts of himself and (the girl), when he deliberately drove towards the railway bridge and struck Mr May's van, that he intended to kill (her)."

The trial continues.
