BROCKTON — A Brockton man sentenced to 17 years in prison was granted bail this morning and a Wareham man was freed minutes later after serving half of his three-year sentence, as drug cases continued to unravel in the wake of the scandal at the state drug lab.

If not for an Immigration and Customs Enforcement detainer on Manuel J. Abreu of Brockton, he would have walked out of Plymouth Superior Court this morning on $7,500 cash bail posted by his family.
