NSW men charged over phone threats to MPs

Two men have been charged with making threatening phone calls to two NSW government MPs including a senior minister.

A 47-year-old man was arrested at Kemps Creek in Sydney's west on Wednesday following reports an MP had received a threatening phone call earlier in August, police said in a statement.

A 58-year-old man was also arrested in Hornsby following reports of a call to another MP this week.

NSW Corrections and Counter Terrorism Minister Anthony Roberts confirmed he was one of those who received a call. It's believed Mulgoa MP Tanya Davies was the other.

Both MPs have publicly voiced their opposition to a bill being debated in state parliament to decriminalise abortion in NSW.

"It's a shame that we have people in our community that, from behind a telephone anonymously, will make vile threats against people that they disagree with," Mr Roberts told 2GB on Thursday.

"There's no place for it in any argument. That's why we have a ballot box, that's why we have a democracy."

He said he was more concerned about the safety of his family and that of Ms Davies than himself.

"It's certainly something we're seeing more and more of," Mr Roberts said.

The accused men have been charged with using a carriage service to menace/harass/offend and will face court at later dates.
