yesterday about blood drops and smears on the defendants' clothing.

Dexter Heyliger, 33, and Sinclair Smith, 28, have denied doing grievous bodily harm to P.c. Joe McRonald after he tried to arrest them for drunk driving on February 25.

The lawyer for the two St. George's men, Mr. Philip Perinchief, has accused P.c. McRonald of attacking one of the men in a "schoolboy punch-up'' and ripping out his dread lock. The Policeman was off duty at the time of the beating.

The trial has been delayed by legal arguments in the absence of the jury but continued yesterday.

Mr. Perinchief sought to establish during cross examination that Government analyst Dr. Alan Young did not know whose blood, or even if it was human or animal, was on a sock and shoe found by detectives.

"It could have been anyone's,'' he said after hearing Dr. Young had not carried out scientific tests on the two items.

However, Dr. Young said he had carried out scientific tests on the matching sock and shoe and found conclusively the victim's blood on them. He said the pattern was consistent with kicking the Policeman.

But Mr. Perinchief said the fact the other two items had not been examined "put into question'' the indication that the shoe was used in kicking an already blood stained surface.

Dr. Young insisted he was satisfied the scientific tests together with his "positive presumptive test'' supported the beating theory.

He said "some blood'' on the defendants' jacket, trousers, socks and shoes had been scientifically grouped.

On re-examination, Crown counsel Mr. Peter DeJulio asked Dr. Young whether he had ever received a request from Mr. Perinchief to test the items of clothing in question.

Mr. Perinchief interjected that it was "immaterial'' whether he had made such a request.

At that point, the six-man, six-woman jury was sent out for further legal arguments.

Heyliger further denies charges of driving while impaired and refusing to take a breathalyser test.

P.c. McRonald has testified he pulled over Heyliger on Middle Road in Warwick on suspicion of drunk driving and was then approached by Smith who was in another car and had stopped further up the road.

He said he showed his badge.

But Smith struck him on the side of the head, he testified, sending him reeling backward, and then kicked him in the groin. Heyliger joined in kicking and punching him until more Police arrived.

But Mr. Perinchief argued it was P.c. McRonald who first attempted to grab Smith by the chest and was facing Smith when the blow fell.

The trial continues today before Puisne Judge the Hon. Mr. Justice Meerabux.
