MANCHESTER — An eight-month undercover drug investigation ended Tuesday with the arrest of three people, the seizure of $37,200 worth of heroin and the confiscation of $16,500 in cash, police said.

The investigation went from Manchester to Lawrence, Mass., and led to an alleged drug ring that distributed heroin throughout northern Massachusetts and southern New Hampshire, according to police.


Christopher Chapman, 22, of 6 Lawton St., was arrested about 9 a.m. Tuesday outside Hillsborough County Superior Court on a warrant charging him with sale of a controlled drug based on the eight-month investigation, police said.

A short time later, the city's SWAT team surrounded his residence, which was then searched. Police said they recovered 12.8 grams of heroin, with a street value of about $1,200, four 8mg Suboxone, worth about $32, and more than $16,500 in cash.

Chapman was then charged with possession with the intent to distribute and possession of a controlled drug. He is to be arraigned Wednesday morning in 9th Circuit Court–Manchester District Division.

Alfredo Valentin, 43, the owner of the Lawton Street residence who also lives there, arrived as the house was being raided and approached officers, police said.

Police said he became hostile towards them and refused to leave the area. He then allegedly began audio recording a conversation between two officers involved in the investigation.

He was arrested and charged with interception and disclosure of telecommunication or oral communication prohibited. New Hampshire requires two-party consent when audio recording individuals, according to police.

He was later released on $1,000 personal recognizance bail, with an arraignment set for April 9.

The investigation continued throughout the day and led to a third man, who was arrested during a motor vehicle stop in Lawrence, Mass., police said.

Members of the Massachusetts State Police drug task force assisted in finding the man, who police said was involved in distributing large quantities of heroin throughout southern New Hampshire and northern Massachusetts.

The man allegedly possessed fraudulent identification, and police said on Wednesday he has yet to be positively identified.

A search of the vehicle that was stopped in Lawrence resulted in the seizure of more than 300 grams of heroin, with an estimated street value of $36,000, police said.
