Police are investigating a rash of recent violent or armed robberies, including four liquor store robberies.

The cases are classified as first-degree robberies.

“Detectives are investigating whether the recent robberies are linked,” said Honolulu Police Department spokeswoman Michelle Yu.

Two male suspects robbed early Wednesday morning a Kalihi liquor store.

One was armed with a “dangerous weapon” during the 1:45 a.m. robbery, police said.

Two women, ages 60 and 38, were in the store at the time.

On Wednesday, a 32-year-old man was arrested on suspicion of first-degree robbery in an Enchanted Lake liquor store robbery, but two men in their 20s remain at large.

In that robbery at 10:14 p.m. Sunday, one of the three men allegedly struck the 62-year-old male owner of Keolu Market with a bottle after the owner tried to stop him.

Two other Windward Oahu liquor stores were also robbed Sunday.
