An internet Romeo dumped after two dates told the woman who ditched him: “I’ve got a gun – I’ll blow you away”.
Mark Mason said he would wait outside the shop where she worked and added: “I’m going to shoot you at 10 o’clock this morning”.
He sent the victim more than 30 messages, posted a picture of a gun and threatened to slit her throat and “f*** her up”.
Warwick Crown Court heard it happened when the victim dumped Mason after a seven-week relationship which began via a dating website.
After communicating online for a fortnight, they met in Wolverhampton and linked up for a second time two weeks later.
But the court heard the victim ended things because she felt Mason was becoming obsessive.
Stuart Clarkson, prosecuting, said: “The defendant was not pleased with that and continued to message her.
“He became aggressive and threatening, including posting a photograph of a gun and making threats to kill himself.”
On April 11 he left a message saying he was coming to Stratford-upon-Avon, where she worked, to wait for her.
The victim was so frightened she did not go to work that day but then received a text in which Mason said: “I’m outside the shop.
“I’ve got a gun.
“I’ll blow you away.”
Mason, 47, of Broad Street, Bilston, had pleaded guilty to putting the victim in fear by harassment.
But he told the judge, Recorder Michael Burrows QC, that she had written to him while he was on remand in prison.
The court heard Mason was jailed for four years in 1994 for making threats to kill.
Mr Clarkson asked for a restraining order to be imposed.
Mason was not represented and sentencing was adjourned to allow psychiatric assessment to be conducted.
