"He is taking my baby out of the house drunk."
"No, I do not want you up here."
"Fuck off this property. You have 30 seconds."
"You do not know what you done. You wait," in a way that the officer took as a personal threat. Mr Nouch heard him say: "
"1251, I'll find you."
"We ... heard that officers attended Mr Blench's address as they were concerned that a violent domestic incident had occurred, or was occurring, involving Miss McGowan and, possibly, another male, and that children were known to be present at the address. "
"There is a breach of the peace whenever harm is actually done or is likely to be done to a person or in his presence to his property or a person is in fear of being so harmed through an assault, an affray, a riot, unlawful assembly or other unlawful disturbance. For such a breach of the peace when done in his presence, a constable or anyone else may arrest an offender without a warrant (see R v Howell[1981] 3 All ER 383 at 389;[1982] QB 416 at 427). A constable or an ordinary citizen has a power of arrest where there is 'reasonable apprehension of imminent danger of a breach of the peace'. This includes where the arrestor reasonably believes that a breach of the peace will be committed in the immediate future by the person arrested (see[1981] 3 All ER 383 at 388;[1982] QB 416 at 426)."
"…every citizen in whose presence a breach of the peace is being, or reasonably appears to be about to be, committed has the right to take reasonable steps to make the person who is breaking or threatening to break the peace refrain from doing so; and those reasonable steps in appropriate cases will include detaining him against his will. At common law this is not only the right of every citizen, it is also his duty, although, except in the case of a citizen who is a constable, it is a duty of imperfect obligation."
"(3) Subject to subsection (5) below, no arrest is lawful unless the person arrested is informed of the ground for the arrest at the time of, or as soon as is practicable after, the arrest."
