A few points;
Para 1:
Sentence 1 should be "... gives A BREAKDOWN OF the number of incidents WITH three different TYPES of crime..."
Sentence 3
the number of car theft and robbery cases in Newport city centre remained unchange, compared to the first time figures .
This should be "... although the number of robbery and car theft cases in Newport city centre remained unchange, compared to the first time figures, the latter case showed a slight increase in the end of the period."
Para 2:
Sentence 1 should be "...figures of three TYPES of crime..."
Sentence 2 should be "...burglary crime AMOUNTED TO the highest number... while in the second place DID almost 3,000 car theft cases HAPPEN... "
Sentence 3 should be "...approximately 600 reportS..."
Sentence 4
these three cases were likely to reduced over four years with the most marked drop was experienced by burglary cases, it decreased by around 2000.
This should be "If analyzed more closely, we have seen a decrease in the number of criminal cases which by far drops around 2000 listed in burglary cases over four years."
Para 3:
Sentence 1 should be "... burglary crime decreased consecutively for over the last five years..."
Hope this helps, eddy suaib.
