A man has been arrested in Leeds on suspicion of making threats against Labour MP Yvette Cooper.
The 59-year-old man was detained on Friday and has since been released on bail.
The nature of the threats has not been reported.
According to the Wakefield Express, the threats had prompted police officers to attend a Labour constituency meeting last week as a precautionary measure.
West Yorkshire Police said in a statement: “As a result of information received in relation to alleged threats against a serving MP, officers arrested a 59-year-old Leeds man in Castleford on Friday.
“He has been bailed pending further advice from the Crown Prosecution Service.”
Cooper has long been vocal about the abuse faced by MPs. In a blog for HuffPost UK in 2017, she wrote: “MPs have had death threats for speaking out in support of different campaigns. Women campaigners have faced vile misogynist abuse. Journalists like Owen Jones are targeted with appalling homophobic threats and harassment.
“We need stronger action from the police and prosecutors when laws are broken. Too often officers investigating abuse don’t even know how the social media platforms work – new training, new guidance and a full review of the law are all needed.”
