ASBOs have been imposed on two men after a judge heard their presence around the O'Connell Street area frightened members of the public.
Gda Supt Sean Ward succeeded in getting anti-social behaviour orders imposed on Dublin men Wayne Donnelly (27), of Riverdale Park, Palmerstown, and Paul Brazil (33), of Carnew Street, Stoneybatter.
Following a hearing at Dublin District Court, Judge John O'Neill granted the ASBOs and specified that neither man is allowed to enter O'Connell Street or the surrounding areas in Dublin 1 between 7am and 9pm for the next 12 months.
Failure to abide by these terms can lead to a criminal prosecution, a three-month jail term and a fine of up to €3,000.
The court action was brought after each man had been repeatedly issued with adult behaviour warnings.
Gda Sgt Adrian Kinsella told the court that on the morning of February 7 last year, Donnelly had been huddled with five others at Lower Abbey Street and passers-by were giving them a "wide berth". He told Donnelly to desist loitering in a manner likely to intimidate.
Last July 22, Sgt Kinsella spotted Donnelly outside a shop in O'Connell Street.
"People were making it their business to avoid the group," he said. Donnelly was searched, but nothing was found.
Gda Daniel Beckett said that last June 4, he saw Donnelly in Lower O'Connell Street "involved in what appeared to be a suspected drugs transaction".
No drugs were found.
The court heard evidence from three gardai about the alleged intimidating behaviour of unemployed father-of-three Paul Brazil.
In one incident, Gda Richard Markey said that on March 19 last year the 33-year-old was seen in Lower Abbey Street, angrily shouting into his phone.
Gda Markey said Brazil told him that he was in the area to buy methadone.
Brazil told his barrister he had never told Gda Markey he was there to buy methadone.
