'The cap' and 'cancer' - codenames used by paranoid criminals for feared mob boss Daniel
Members of Daniel Kinahan's gang are so afraid of him that they refer to the crime boss only by a codename when discussing drug shipments and other crimes.
Thugs working for the cartel have started calling him 'The Cap' for fear of incriminating the mob leader.
This includes all forms of communication including face-to-face conversations, text messages, phone calls and encrypted Whatsapp chats.
The nickname originates from Kinahan's love of caps.
The 39-year-old is rarely seen in public without a baseball cap or a flat cap which he famously wore to the funeral of murder victim David Byrne (35) who was shot dead at a boxing weigh-in at the Regency Hotel early last year.
Sources have established that foot soldiers working for the ruthless gang fear they will be branded a "rat" if they mention his name when discussing mob business.
"They are so paranoid about using his name and getting blamed for things going wrong that they won't use it at all," said a source. "They just call him 'The Cap'.
"They think that using a codename will protect them from ever being blamed for ratting to the cops."
Daniel Kinahan - whose father is Christy 'Dapper Don' Kinahan - uses the name Donnelly when travelling around Europe and the Middle East to avoid detection by killers linked to the rival Hutch mob.
His brother, Christy Jr, has used the same fake name in the past.
"Daniel knows that he remains the prime target for the Hutch mob," said the source.
"They've been gunning for him for over 18 months now and he knows that if he lets his guard slip, even abroad, he will be taken out."
Kinahan was the primary target at the Regency Hotel shooting in February last year when five armed men stormed the Dublin venue and opened fire.
He managed to escape the hotel through a back entrance as one of the gunmen shouted: "He's not f***ing in there. I can't find him."
The gang boss remains at the top of the Hutch hitlist.
Kinahan target James 'Mago' Gately - who cheated death when he was shot five times last month - has warned gardai that the deadly feud will not be over until Kinahan is shot dead.
"We will not rest until Daniel Kinahan is dead," Gately warned detectives when they visited his Coolock home in the aftermath of the Regency Hotel attack. "He caused all of this. It won't end until he's in his grave."
After last month's botched murder attempt by a professional cartel hit team at a busy petrol station, Gately (30) vowed Dublin's gangland feud would continue.
Speaking from his hospital bed with a bullet lodged in his jaw, he told gardai: "I am not going down without a fight."
Despite being referred to as 'The Cap' by his associates, low-level criminals in Dublin allude to Kinahan as 'Cancer' because his murderous cartel are so lethal.
"The low-level street crims and drug addicts just call Daniel 'Cancer' because of all the people that his gang have killed during the feud," said a source yesterday.
So far, 12 people have been murdered in the bloody Hutch/Kinahan feud.
In May, the Herald revealed that detectives had received information about Kinahan's direct involvement in a plot to murder a member of the Hutch gang.
The significant development came after it emerged that an informant told gardai he had been ordered by Kinahan to murder a leading member of the rival Hutch gang.
Sources say the individual, who is facing serious charges, has told of Kinahan's direct involvement in the murder plot.
Gardai believe this is proof of the cartel chief's central role in the ongoing Hutch-Kinahan feud.
